Glad to help, thanks for watching!

[@daniellindsay3145]

Hey brother. I just wanted to say thank you! I’m building a boat from almost scratch! Your videos on fiberglass and painting and epoxy has helped me tremendously. I can literally hear you while I’m building almost guiding my hands. It is a stitch and glue ply on frame hybrid drift boat for fishing. Without these vids I would not have as many compliments on how she looks

[@FishBumpTV]

That is awesome!! That sounds like a very cool project, for sure! Glad the videos are helpful, and I appreciate you watching

Peel Ply video please ! ❤❤❤

[@FishBumpTV]

Just uploaded it. Enjoy!!

[@andre-louw]

I use vinyl ester as an interface layer over the epoxy before applying the polyester gelcoat. Always produces success.

[@jimp.7286]

Add me to those wanting to see peel ply vids! Peel ply on somewhat complex curves? I've not used it before. I read somewhere that's a no. But your vid made it look do-able. Thanks for priceless content here. Cheers. 👍

[@FishBumpTV]

Thanks! I will be starting work on it once I get some shorter, product review videos done. And hoping for some cooler weather for the demo phase of the project. Tyvek suits and full respirators in 95 degree heat and 90 plus percent humidity is not safe or good for your health, not gonna risk a heat stroke just to keep up a upload schedule. I hope you all understand.

[@FishBumpTV]

[@cargogamer7261]

You can test by leaving 2 samples in a bucket of water for a few days. Possibly even a designated spot in a lake or sea since that's more realistic, then come back to them after a few weeks or maybe even months

[@FishBumpTV]

Great suggestions! Thanks for watching and commenting!

[@WilliamGushulak]

with this new product that you are promoting, do a flex test, 6-inch wide, 4- foot long 1/4- inch thick plywood and epoxy it like you showed, with the gel-coat as the top final layer, two coats, then fix one end to a solid fixture and with the other end clamp/screw down a solid board to it, 2x4 or some just solid and do a 90 degree twist both ways, making it a 180 degree test. I am very interest in the results. if this product is good it will not break adhesion.

[@FishBumpTV]

Great suggestion! Thanks for watching!

[@JeremyDWilliamsOfficial]

Help... First, love the videos! I really could use some advice. Fibreglass boat with a white gel coat. It had some chips and minor cosmetic issues including some small stress cracks. Not too many thankfully. Used a die grinder to clear them out back to the epoxy, acetone to get any wax off and sanded it to get good rough surface. I first mixed the gel coat with half gel and half West Systems 406 colloidal silica to make it a peanut butter consistency. I tinted a small batch of the thickened gel coat. Managed to make it a perfect colour match. (skill? or luck lol). Made enough for 3 times what I needed. Used your tape trick. Filled with gel coat all the areas needed doing. I used up just under half what I made. But..... ugh. I didn't put in enough hardener, or maybe none... my bad. After a few days it hadn't hardened at all. I dug out as much of the unhardened gel coat as I could, used the die grinder to remove rest of it, and made repair areas slightly larger (1/16" or so bigger, no big deal, just to make sure I got all the unset gel coat out). Cleaned it out again with acetone. Roughed it up again. My question: How long can the pre tinted white thickened gel coat last? (no hardener added). I'm about to try again (with more hardener this time lol) but the batch I mixed (about the size of a golf ball or two) has a crack from I assume drying. It was put in a small plastic container so it shouldn't get any air other than that in the container. It's been two weeks since I tinted it. I really don't want to mix another batch as I doubt I'll be as lucky matching the color a second time around. My gut feeling is that it should be fine as it's just gel coat with tint, but the crack in it caused some concern. It was a lot of work to clean up the mess I made, I would prefer not to do that again lol I did some tests this time for the hardener amount. It was hard to calculate as it's such a small amount. My test with a sugar cube sized amount of gel coat with four drops of hardener seemed about right. After 20 minutes it seemed pretty firm. About 80 degrees here. Any advice on that or anything else would be much appreciated and most helpful :) Thanks again @FishBumpTV

[@FishBumpTV]

Glad you are enjoying the videos! Sorry to hear you are having some gelcoat curing issues. I don't typically use thickened gelcoat that isn't fresh, so hard to say for sure how it will do for you. Sometimes you can add a bit of neutral or clear gelcoat or polyester resin to a mix like that to help with it having dried out, but without changing the color at all. You could also add a small amount of fresh white gelcoat back into your thickened gelcoat mix to freshen it up. That shouldn't change the color much, and will help bring the original gelcoat back to a nice creamy consistency. As far as catalyst for small amounts like that, a general rule of thumb is 10 to 12 drops per ounce, or 10 to 12 CCs per quart. 4 drops for a sugar cube size seems like a touch high to me, 3 drops in high temps should do, that will also give you a little more working time. Although it is better to slightly over catalyze than under catalyze.Also,be sure to thoroughly mix in the catalyst with the gelcoat or you will have curing issues.I hope this helps, and thanks for watching!

Joe, great video for bonding Gelcoat to epoxy. I’m in a project and will use it! You ask for test suggestions. I suggest comparing one test piece with the binding product to one without the bonding product. Then do the glued bolt, chip away and feather sanding test on both.

[@FishBumpTV]

Great suggestion! Thanks for watching!

[@ropeman3916]

[@FishBumpTV]

[@ttwil9810]

Yes you do as when I worked at Current Designs with our out rigger boats built with carbon and epoxy and we used west sys also but I believe if I remember right, we had a clear coat we use to spray for bonding with epoxy will check with former co workers and get back to you

[@FishBumpTV]

Thanks for the info, and for watching!

[@robertpendzick9250]

Instead of bonding the bolt to the gel coat surface, prior to gel coating cut the bolt head into your testing piece. Now apply the gel coat, let set, and then pull the bolt head out. You will test how much of the gel coat is pulled off as the bolt head pulls through. Does it sheet off a large area? (poor bond?) Does it crack only at the head? (good bond) Does it bubble a large area? (Elastic coat but not well bonded)

[@FishBumpTV]

Good suggestions! We may try some out in another round of tests. Thanks for watching

[@joeg1980]

Boatworks today made a few videos on this also. I noticed some companies offer an epoxy top surface or an epoxy gel coat. Never used them but I am interested. I use polyester fabrics for peel ply. Just remember all polyester fabrics aren’t the same. There are so many types of polyester fabrics.

[@FishBumpTV]

Good point! Thanks for watching and commenting!

[@bullthrush]

Neat product. An interesting test would be a heat gun simulating a too close exhaust manifold (probably late in the testing schedule).

[@FishBumpTV]

Thanks for the suggestion, I might try that in one of our long term tests of the epoxy tie coat. Appreciate you watching!

[@jeremystory6981]

[@ttwil9810]

peel ply used it when seaming kayaks for a smooth interior seam also when ending a open lamentation run or in layup to minimize bag lines when vacuum bagging . Simple to use as a brush is all you need, lay peel ply over edge or over piece wanting to make smooth and to assist with air removal. Start in center and brush to each end that simple

[@FishBumpTV]

Yep, that's some good info! Thanks for watching and commenting

[@CRAIGMCLEAN-ANDERSON]

A benefit, and some might say the purpose, of peel ply is that the amine blush rises to the surface through the peel ply and is removed when you pull the peel ply off. If amine blush is the reason for the failure of gel coat over epoxy, then there shouldn't be an issue if you remove the amine blush right?

[@FishBumpTV]

Yes, I agree the blush removal is a big plus. Thanks for watching!

[@jonnooney7102]

I found that using a wire mesh vegetable strainer to run the old gel coat thru before catalyst is added saves a lot of aggravation from all the chunky bits that develop in an older previously opened container. The automotive paint strainers are just too fine for gel coat. Got to have a bucket of acetone to clean the strainer with after use.

[@FishBumpTV]

Cool tip! Thanks

[@diggy-d8w]

I am glad that you made this video. I have been watching (subscribed) since the first video for the 2900. I have been researching and planning a boat build and wanted to use epoxy but worried about compatibility issues. I know you are busy but would appreciate if you could look over my plans, to date, and give me any feedback or suggestions that you have.

[@starrider4878]

I’m going to practice learning gel coat on a surfboard. The tip is damaged and a few other dings. I’m thinking that structural putty and epoxy is looking sweet for my base then go for the gel coat on top. 🤙😎

[@ttwil9810]

with sticky gel give it a wipe with acetone let dry and then sand min clogging to none . As I use to use vinyl ester for edge repairs on Kayak molds , Which I use tape to hold repair(no paraffin wax) wiped with acetone then sanded and polished to a high sheen to match tooling gel. And was much stronger than a gel repair as I had to prove to my employer as I did with many processes they put on my plate to conquer.

[@FishBumpTV]

Thanks for the tip and for watching!

[@keithawhitley]

Do an experiment with gel coating over regular epoxy and see if it sticks. Let the epoxy cure for a week, sand and apply gel.

[@FishBumpTV]

Thanks for the suggestion and for watching!

[@cargogamer7261]

How many layers of fiberglass do you need until your fully waterproof?

[@FishBumpTV]

That can be a little difficult to answer exactly. It would depend on the fiberglass fabric used, type of resin and the experience level of the person doing the work. Maybe I could do a video on that topic. Thanks for watching!

[@DarrellMattan]

Hey great videos, question - what do you use to thin gelcoat.

[@FishBumpTV]

Thanks! Styrene, or a clear gelcoat additive like air dry coatings, patch aid or Duratec. I hope this helps and thanks for watching!

[@gunnarfernqvist4896]

How would it work to use a layer of regular vinylester as a bonding agent between epoxy and gelcoat instead if we can't get hold of this brand? It looks thick and glossy when applied on a flat surface but how would it spread out and look on a vertical surface for example? Would it all be a lump at the bottom of the surface or would it look as even and as good as this?

[@FishBumpTV]

Vinyl ester is closer to epoxy, but still may not bond properly. The system 3 sb112 can be applied vertically, but you would apply it in two thin coats, vs 1 thick coat. I hope this helps and thanks for watching!

[@gunnarfernqvist4896]

@@FishBumpTV I’ve seen other boat building channels here on YT that use vinyl ester instead of epoxy to be able to use gel coat and top coat (flow coat).

Make a hatch lid for the Buskins 29 out of west system epoxy. Put a tape line down the middle, Half with tie coat half without. Gelcoat the whole thing to match and run it on the boat. Then you have a polyester vs epoxy vs tie coat real world comparison. Totally understand the cost of things are out of reach re hard top. MAGA I think the project boat will be a yuge bump to your channel

Everyone wants me to use epoxy until I tell them how much extra I have to charge for it.

[@FishBumpTV]

Haha, I hear ya! Not cheap!

[@ab_ab_c]

It appears to me that the gel coat is relatively easy to scratch off the epoxy. Is there another coating that can be applied to the gel coating to make the surface harder & more scratch resistant?

[@FishBumpTV]

I was probably putting more force on it than you realize. It reacted about the same as gelcoat does when applied over polyester or vinyl ester resin, which I thought was good. I will be doing some more long term testing of the System 3 products, so stay tuned!
