YOU ARE PROBABLY USING THE WRONG RESIN! Fiberglass resin Selection Guide & What to Know (2024)

Which fiberglass resin is best for your next project? In this video we will test and talk about the five most commonly used fiberglass resin types, and there pros and cons. We will also wet out some 1708 biaxial fiberglass with the different resin types, let it cure, then test it to failure! This should be interesting and helpful especially to the DIYers and those new to fiberglass and epoxy work. So sit back and enjoy as we mix up and test some resin. If You find this video helpful, please consider liking, sharing, commenting, and subscribing to the channel. Thanks for watching!

[@FishBumpTV]

Thanks for watching

[@koji71]

Epoxy can take 6-10 days to “fully cure” depending on ambient temp. But once it finishes it is much harder. Polyester will continue to cure for months (and shrink on a micro level) which is why it tends to have less adhesive properties. If I had to guess I would say that epoxy was 2-4 days old. Your videos are awesome! I will be subscribing to the patreon here shortly

[@FishBumpTV]

Thanks for your thoughts

[@nico-bf1kr]

Also some epoxy need to be cured in an oven. I hope this is not one of them.

[@Cheers_Warren]

I like that you found some resins available to the diy market. I’m A polyester resin man all the way having been in fiberglass industry years. The cost for diy resin is crazy high compared to industrial pricing. I guess you don’t remember the days when we had to use paste or powder BPO catalyst in sticky vinylester resins ( derakane) , ever since they came out with the AME2000 VE resin that used MEKP the VE world changed! The things I don’t like about using epoxy is it’s much slower too work with , it’s very expensive in small lots, It’s more toxic ,if you get it on your skin , espically when sweaty you can get sensitive to it permanently! Not good! Good video! Cheers Warren

I used vinyl ester for wrapping and adhering the engine and tranny mounts on my Shamrock, which were then gelcoated. The only drawback is the short shelf life compared to polyester. It has to be fresh, and used promptly.

[@FishBumpTV]

Some brands have better shelf life than others. I have been very happy with the vinyl Ester we have been using recently.Overall vinyl Ester is a great option where you need strength and waterproofing, and also want to finish with gelcoat. Thank you for watching and commenting!

[@christopherbowersdresser4188]

** to add. epoxy resin wont destroy foam, and is the go to for carbon fiber that will be naked. poly and vinyl ester resins are great for most everything, except laminating foam, unless some melting of the foam is part of the plan like bonding to the hull and ring deck. ive built boats, automotive body kits, and speaker enclosures out of poly / vinyl, its cheap and strong. when shaping foam for a pattern i use epoxy to seal the foam before applying more glass / body filler etc. ive used epoxy to seal counter tops, fill voids in lumber before milling into furniture, and for materials like carbon fiber / kevlar where the aesthetics of the materials are desirable. i had some gold carbon kevlar years ago that was pretty cool left over from gov boats.

[@drifter9425]

I thought epoxy wasn't UV stable Epoxy paint isn't as UV stable as Urethane/Polyurethane

[@christopherbowersdresser4188]

@@drifter9425 youre not wrong, but its the only real option for clear resin. if clear isnt a factor than by all means use poly etc.. the carbon / kevlar boats ive built in the past were gel coated to look like any other center console boat and laminated with normal production resin. also, anything naked carbon is going to be expensive as all hell and probably well taken care of / covered. to mitigate uv damage.

[@drifter9425]

@@christopherbowersdresser4188 I'm a lifelong auto body technician and some customers buy the 2000.00 carbon fiber hoods and expect it to hold up to everyday use but if it's something that's gonna see lots of sun I use top end automotive Polyurethane clear on them and it holds up pretty good

This has been very interesting. I'm planning on building a kayak very shortly. After seeing this video I now know what resin I will use. While watching this a thought came to mind, and I would like your opinion. This will probably be be very different than what is typical. Have you ever thought of applying a coat of contact adhesive to a plywood boat, and then lay fiberglass into the contact cement as a first layer?

[@FishBumpTV]

Glad you are enjoying the videos! No, I have never seen that done before. I think I would stick with resin personally.

Just a thought...maybe you can find someone with an old "project" boat to donate to the shop as a way to demonstrate different repairs/techniques.

[@tmc.318]

Could you do a video or comment on boat flex allowances, areas and necessity? I am in progress on a transom replacement from rotten wood to Coosa on a 25' plus twin outboard glass bracket center console boat. I want to terminate my stern floor liner directly to the transom (via glassed in coosa bracing). It used to have a liner to transom gap, but I want to do floor drains via directly cut slots straight out the back. The previous gap there (pvc pipe out) was a major source of my leak that rotted the wood. If I bond the floor directly to the transom am I killing a necessary flex and may end up cracking floor, stringer or transom? I'm also planning to do a permanent glass and bolt bond of the engine bracket to transom. You have by far the best show on boat works and I appreciate your longer and encompassing demonstrations and explanations. I am doing the work and you are helping immensely. Huge fan here. Thank you!!!!!!!!!

[@FishBumpTV]

Sounds like a great project boat you are putting together! We almost always glass floors to transoms, as well as glass splash wells and other structural parts together. There is always going to be some flex in fiberglass parts, but in my opinion you would want to minimize it. When parts flex alot, they usually fail at some point. There are several videos in our custom 29 boat building series that shows us glassing floors and splash wells, etc to the transoms. I am sure these videos would be helpful.Of course every boat is different, and you have to decide what is best for your boat. I hope this helps, and thanks for Watching!

[@tmc.318]

@@FishBumpTV Appreciate that info. I've actually owned this boat 22 years and hope to have it another 22. I've been watching your 29 boat build but sometimes, like any other series on Ytube, it's hard to get the videos in sequence and find myself fishing for it. I know you can't usually make a link to the next video because at that point you haven't shot it yet, but maybe you could always have a link to the previous video so we know when we skip to far ahead. Had my semi pro glass guy helper with me yesterday and today (at $100/hr) and he's asking me how I've come up to speed so well and challenges me on some of it. It's because of you man. I wasn't fully on board some of his work and I went forward at 5 AM today before he got here and made some nice advances, like more glass structure in the transom and bracket areas where the bolts run through. And today we worked together and glassed and bolted the bracket to transom. It's better than ever. Many thanks and when I get through this I promise to send you some thank you $ too if the boat survives the beat down test run. You are awesome, keep it up!!!

[@FishBumpTV]

When I repaired my pool step I used 1708 and I believe epoxy resin. Then painted it with Total Boat gel coat with wax. That was 3 years ago and it has started peeling. From your previous episodes, you mentioned that you should never gel coat over epoxy. Could this be what’s causing the peeling? How can I correct this? The patch itself is strong and holding up well.

[@michaelh7527]

I watched your video and loved it! But I'm hoping you can give me some advice since you obviously know what you are doing. I have a small 14ft fiberglass river boat from the 1970s. I replaced the transom about 4 years ago with two 3/4 pieces of plywood that I epoxied together and epoxied to the back skin. I used epoxy and some fiberglass cloth given to me to create a back skin. I'm about to remove the outboard motor and install a surface drive mud motor that is about 70lbs heavier. I want to beef up the transom. I'm thinking about using epoxy and adding around 3 layers of fiberglass cloth to the edges. I'm also thinking of adding a couple of 45 degree braces that will be secured to the transom and floor. My problem is that I am hearing all sorts of opinions on how I should do this. Some are saying just use csm soaked with epoxy, and others are saying use 1708 cloth.... I would love to hear your idea on what I should do.

[@FishBumpTV]

Sounds like you have a solid plan overall! If you are using epoxy resin, and your goal is to add strength, then 1708 would be the way I would go on my own boat. The transom is an area that we always overbuild, when in doubt add another layer or two. I hope this helps and I wish you success with you project!

[@PremierGraphicsWraps]

The epoxy that has some flex, would it be less of a liability on a transom? If it allows for flex, would the base of the transom become strained, or does it allow for the natural flex of said material to absorb the stress properly?

[@jimclark2824]

Thank you for the video...

[@FishBumpTV]

Welcome!

[@TheSpadre]

I don't think the styrene-based resins were fully cured. Likely they would have performed more similarly to the Epoxy if they were fully cured. I think also for repairs, the secondary bonding strength of Epoxy gives it the upper hand and why most DIY folks tend to use it more. The only downside is for repairs when gel coat is involved.

[@FishBumpTV]

Thanks for your thoughts

[@lawrenceveinotte]

[@Jknox1030]

Is there ever a scenario where you would use different resins as you build up layers? you mentioned having 10 layers on the floor of your build, would you ever mix as you build up those 10 layers?

We usually laminate with only one type of resin, but sometimes you will do a vinyl Ester skin coat. I just wanted to show that many of these resins are compatible with each other, and can work together if that if what you had to work with. Thanks for watching

[@PartikleVT]

Hey! I'm gonna have to ask this. Finding vinyl ester was a bit tough, but I managed to find some composite factories that produce it in small enough quantities for my personal use and it is cheap. I'm talking polyester resin cheap. Why would I ever use polyester resin when vinyl ester is just as cheap and also better (in that its not subject to osmosis and rot like poly). Is there any application where poly is "better" than vinyl?

[@russellfaith8959]

@@fiberglassguru The are submerged in the water 24/7. I figured bottom paint would be the best option. Is there something else you would suggest?

[@FishBumpTV]

The vinyl Ester resin is the is going to be be the best for that application in my opinion. It bonds very well when used in repairs, it is compatible with csm or mat fiberglass and it is a great water and moisture barrier. I hope this helps and best of luck with your project!

Curious on the vinylester vs iso polyester shrinkage as I generally use either iso poly or epoxy. Post cure I find iso polyester leaves considerable fibre print through.

Joe thank you for the effort you put into your videos ,much appreciated. I have a quick question I had damaged the bottom of my boat on the ribs no holes would it be best to repair with 1807 or 1808 and use an polyester resin and then mix up a little apoxy resin and just apply over the repaired area to prevent water intrusion

[@skilletojones2005]

What do you think about laying up a new floor using polyester for the first couple layers and finishing with vinyl ester? I'm using csm with 24oz roven.

Great video thanks for the sharing information. I got a question where you get the red dye I would like to get some for myself. Thanks appreciate it.

[@FishBumpTV]

I get the red dye at our local Advanced Plastics in Elberta, Alabama. Most fiberglass distributors should also have it if you ask for it. Hope this helps. Thanks for watching!

I am about to do transom and stringers. I got a 5 gallon of poly resin but it says perfect for marine and auto (above waterline). The guy I got my resin from runs a repair shop and says he uses it but I am hesitant. Is this okay or should I look for a different resin? The one I got is ClearCote General Purpose low profile laminating resin. Product code is 124445 Love the videos! They've helped a lot! Thank you!

[@FishBumpTV]

Glad you are enjoying the videos! Sorry, but there is no way for me to be familiar with every brand of resin and its working qualities. I can give you all some information and suggestions based on the resins in our videos. But beyond that you will just have to do some testing and research yourself. Wish I could be more help. Thanks for watching!

[@SlicksOutdoors]

No gel coat over epoxy so could you epoxy then top coat with vinyl ester then gel coat?

[@FishBumpTV]

No, not even vinyl Ester is recommended over epoxy. I do have a product I will be testing very soon that is designed to solve the compatibility problem between epoxy and polyester-vinyl Ester based resins and gelcoats, so stay tuned!

[@SlicksOutdoors]

Thanks for your reply, I’ll be looking forward to the new videos.

Do you have a video on flotation foam installation methods? Thank you.

[@FishBumpTV]

I plan to make a flotation foam video soon for you guys. Thanks for watching!

Does anyone have an opinion on Epodex Epoxy Laminating Resin? I am considering using it on a 22-foot plywood sailboat build, and I would appreciate your thoughts/feedback. Thanks.

[@danielschwab1546]

Hey capt joe, just want you to know loving all the vidios learning a ton just picked up a 1993 sea ray express cruiser 250 sat for awhile came from lake michigan spent the last 2 years in lake O in florida. never been in salt water it only has 486 hours motor is sound hull is solid from research specs say it was made with vinylester resin wich is a good thing I suppose watching your vidio with the can of beans coud not be more true. the boat had a alot of decorative panels plywood wrapped with foam and vinyl and carpet glued to the glass I ripped it all out.one of the shelves had resin rolled on no rot, the other not coated rotten I want to cut the shelves off close to the hull and grind as close as I dare my question to you is can I use a laminating resin with mat on the curves I also want to epoxy some rips of plywood for mounting some under gunnel rod holders to mount on due I need to cure the poly before I go over with epoxy and 1708 or can it be tacky sorry for the long story just want to do it right. Thanks dan

[@patricktoulze1274]

Good, Video, any of these are compatible with construction foam board? I guess Epoxy? What about Acrylic Resin?

[@FishBumpTV]

Thanks! Epoxy is likely to be the most compatible.

[@clarkleininger6560]

I want to do a webbing/splatter finish on my current project. I don't have a sprayer and don't want to invest in all the necessary equipment and additives for a small project. I bought a can of Montana Marble Effect Acrylic spray paint which will produce a similar webbing effect. Will acrylic paint stick to gelcoat? Thanks.

[@FishBumpTV]

I don't know if that could work or not, I have never tried doing that before. You could always do a test panel and see before doing the whole thing. I imagine even if it does stick to the base gelcoat that it would not be as tough as gelcoat splatter in the high wear areas. Hope this helps and thanks for watching!

[@derrickaldanajr]

Im trying to fix a headliner in my car want ot a little stiffer im things the first on or the midle one what do you guys think

[@FishBumpTV]

The middle one, which is a vinyl ester is my favorite all around resin. I hope this helps and thanks for watching!

[@jim-jf5rn]

I have a ganoe that I am planning on redoing the transom and the Bow Ridge. Which resin do you recommend for both? Also, would it be okay to add pigment to the finishing resin?

[@FishBumpTV]

I really like the vinyl ester resin from Fiberglass warehouse for just about everything. I don't usually add pigment to resin, I would recommend using gelcoat in the correct color if possible. Thanks for watching!

[@user-ft3lo7jw2x]

I am going to build an 8 foot long by 36 inch high and 40 inch wide box. I think out of 3/4 inch plywood. What is the best supplies to have for this?

[@jasonsmith7809]

Im trying to fix a transom that has delaminated in a small area. I was thinking of injecting a resin into the split from the top and then clamping. Would you choose vinylester or epoxy? Love your channel!

[@FishBumpTV]

They could possibly both work. I might lean towards epoxy on this one though. Just be sure there is not any moisture in the delaminated area or nothing will stick. I hope this helps and thanks for watching!

[@jasonsmith7809]

@@FishBumpTV Thanks again for all the help. You are awesome!

[@williamknight3772]

What would you recommend to use on the bow and walkway of an older boat? 1974 Trojan f25

[@FishBumpTV]

I really like the vinyl Ester as a all around quality resin, it does many things very well. Thanks for watching!

[@brandonhenderson7020]

I cant find any videos on repairs on seadoo cm tech hulls skin or what to use to reinforce the inside

[@Gejoepee]

Thanks for the information. Which one do you recommend for automotive exterior body kit applications

[@FishBumpTV]

Glad you are enjoying the videos! The iso tooling resin and the vinyl ester are really good. Epoxy could also work, but you would have to use epoxy based fillers and primers if you choose to work with the epoxy. I hope this helps, and thanks for watching!

[@davidtornberg8060]

Could you talk about the shelf life of the resin. I have used vinyl ester before and that has a short three month shelf life if I remember right. I have some west system epoxy now for a over two years will it still be alright to use?

[@kkutube1972]

Where can I buy the dye, just want to make sure i am using a compatible version. Thanks.

[@FishBumpTV]

Fiberglass Warehouse should have some red dye. They also offer a discount code for fish bump tv viewers. Hope this helps and thanks for watching!
