Painting helps although it can be avoided if the primer is the correct on(low load) and well polished and sealed. In my humble opinion of someone who has worked with mould making for over 20 years you are missing a couple of steps. Bee wax and PVA applications. After applying Freekote release agent run over with no less than 6 coats of bee wax. First application with strokes in the longitudinal direction, then across, and so on... Spread the wax as thin and as generously as you can and then buff it off with a clean cotton rug. Repeat the process 6 times and let it set for a couple of hours to allow any solvent on the surface to evaporate. If you have extra cash to expend you can employ a more sophisticated product like carnaúba wax for mould release. This is what the aerospace industry employs... The wax will flatten all the irregularities that the sealant didn't and allow for better results. If the above still doesn't work then it might be that your polishing is not thin enough. In this case, apply PVA release (with a spray gun - read the prep and working instructions) before starting with the tooling gel-coat. By the way, try to use the correct gel-coat for the moulds. They are more expensive but last longer. I would also like to suggest another two directors for when making your moulds. First: you can make epoxy parts from polyester moulds. Polyester will not only be cheaper, but way easier to work with. Second: NEVER use cloth when laying moulds up. You need the fibre to be in short segments to allow for accommodation and to avoid bridging in the internal corners. Also, try to lay the first play with the finest matt you can get and leave it to set accordingly. This will help in avoiding through -printing of the fiber strands on the internal face of the mould. I hope this helps and I look forward to your final composites results.😊

Use PVA as a release agent x 3 coats, fist one light mist and build up, this way you dont need to paint the part. But Don't go to Heavey 3-4 coats max. use plasticine around the handle as that is a grab point, use a glue gun to hold the sign board on. Another thing is called Exotherm if you have not let your plug cure properly, it will key to the plug. dont use a cut brush for laying gelcoat, only for layup. and keep the light (UV) as it will pre-cure to early. do a pre wet out on the mold, will help the resin adsorb up into the cloth under it. Sorry, just trying to help.

I’m not an expert but someone above mentioned it eating into the primer, as an automotive painted this does make sense to me. I would reach out to Loctite and ask if that is why it did that. Perhaps primer is too porous and the release is bonding to it. Really hated to see all of that hard work for that result. You will get it figured out, keep up the great work.

I always wax and use PVA on my plugs, then chemical release on the mold for your actual carbon parts. I never had any luck with chemical release on the plug. And why no chop strand mat for the first few layers? It will go much faster with less risk of air bubbles underneath. Its the normal process for mold making. Yeah, as everyone else has said, no primer finish, even a 2k primer is no good. Primer does what primer does, leave a good surface for paint to grab on to. Using a few coats of some 2k clear then polishing it up is my go to.

And with PVA over the plug you are able to drive a wedge in between and pour some water in to dissolve the PVA. And the plug will pop right out of the mold. Nice and easy, with less risk of damaging anything.

Primer is designed to grab unto whatever it touches, especially if it is fresh primer. So the black coat will hook into it as soon as it is applied. You need to paint and or clear the parts or sand them to bare metal before you apply the resin and cloth. Sorry this happened, but it's a learning process. Keep trucking, bro.

Following closely as I am about to undertake the same type of carbon project. From my understanding and some previous experience with similar issues, it comes down to the primer. The primer is porous and designed to have something stick to it (the top coat). So because the plug (tailgate) isn't sealed then the Frekote gets absorbed into the primer rather than sitting on top of it. So you need to pain the parts to effectively seal the part, then the Frekote can sit on top of the paint and act as that separation layer. Don't think it matters what your top coat is 2 stage vs single stage, but it needs to be fully painted and sealed.

Since your primer is still not a gloss smooth surface you need to use a better release. Specifically spray wax. That will allow you to keep things primed and still have a great release.

Tofu Auto Works (as suggested below) is a great suggestion. There's another Canadian channel Throttle Stop Garage who made a carbon fiber body for his Volvo Amazon. He also used Composite Invision products when he did so. Lots of great (and pretty technical) info over there. Even tho you didn't seem to use them, I'd suggest picking up some fiberglass rollers. If you gte the metal ones, you can soak them in acetone when you're done. Much easier than cleaning plastic ones. Should help avoid bubbles in the future (just in case.) Good luck! You got a new subscriber today.

I use a paste wax for molds. Partall #2 works for me. I've even used minwax paste wax before. You may want to make sure the epoxy sealer is fully cured before doing the gelcoat. Also, if you need to stop putting resin and fiberglass down, just give it a good scuff with sandpaper to give a mechanical bond to the layer before. Also you might want to look into using a chop gun for building the mold out instead of using multiple Layers you can really bulk up a mold quickly and you have a long way to go. It's messy but it's a lot less work. Good luck

If you plan on a high temp cure for the carbon you would want to make a few changes to your mold. It should be vacuum bagged as any air trapped in the mold construction can expand and damage the mold or product. Current one might be ok for a one time use however. Also, the mold should be cured to at least 50 degrees F above the intended cure temp of the product. As the mold will soften near its highest cure temp. Probably too late for a proper cure now, and without the initial bagging is risky.
@FullSpeed_only

Good Points. I’m no Expert, but fought with a Bunch of small Parts/Molds: There should be Resin for high Temperatures, that isn’t Aluminium filled. Any Filling Material makes it harder to wet out the Layup. Al Filling can be pretty good, but not when you want to wet out the Mold Layers, especially without Vacuum. The Product is probably specified for your Use, but there is quite a Difference between what works well for a Pro and what is forgiving small Errors. I always try to heat it to the highest Temperature that looks safe before Removing. The Resin I have Experience with gets softer with Heat and "cures" once again. Normally there are Charts for good Products. Otherwise it will soften once you bake the final Part. Stuffing the Metal Part back into, strapping the Mold to it and slowly heating it might give you the Benefit still and as @robb1165 said there is the Risk of expanding Bubbles. When you heat it without your laminated Part inside you have the Opportunity to repair Spots that pop up and avoid the Issue in your final Piece. A painfully slow Heat-Cure can give you the Chance to watch for Signs and drill tiny Holes into Flaws before the Air/Gases do to much Damage: Metal Part in, slowly to 30°C, slowly cool of, Metal Part out, inspect Repeat with +5/10°C each Time until the different Heat Expansion Rates or the Heat Resistance of one Component looks like the Limit.

If you are making carbon fibre parts in the moulds at elevated temperature you should make the moulds from carbon fibre not glass because the glass mould will expand further under heat. The part will cure but then thevmould will contract further than the part possibly causing issues. Also as someone said previously using vacuum during layup or even vacuum infusion method to make the mould would reduce the chances of voids in the mould blistering during curing a part. Keep at it, good effort so far👍

I think you’re right about the temperature changes, not sure if that epoxy heated up, there’s a name for it I can’t remember right now, thermal something?? But the metal heated up and it got cooled off and shrunk, causing the delaminating. Or could have been a spot with dust underneath. At work, we monitor surface temperatures, ambient temperatures, dew point, humidity. All has to be in spec. The product data sheet has everything you need to know for any epoxy. This kind of coating isn’t house painting.

Use PVA as your release agent. If you want to take a break from laminating use peelply to cover the fresh laminate and let cure. Next laminating session remove peel ply and continue your layup. When applying the peelply make sure it is completely wet out by the laminate below. The peel ply is meant for this exact purpose. Peelply is used to avoid sanding for the next layer. Do not use a peelply with a release agent as it will delaminate, use a non coated peelply. My schedule goes for 2-3 days to avoid exotherm, shrinking and warping. The 2 layers of surface coat, 1 layer glass veil or light glass cover with peelply and let cure over night. Next day remove peelply and small molds get finished on this day large molds get 1/2 of the glass then peelply again and the next day finished and bracing put on the backside. Hope this helps. If you want some more in depth advice hit me up.

Best mold release if ever used is Ease Release 200. As far as I know uncured resin will still bond to cured resin so the delamination of fiberglass layers wouldn’t have been caused by taking a break. What I believe happened was you may not have saturated the fiberglass enough. Aluminum filled epoxy is very viscous and doesn’t travel through materials as well as pure epoxy. Also, you handled that failure like a boss. Personally, I would have lost my shit and quit for a day 😂

Polish it like you are entering it in a big car show. The smoother cleaner it is, the better for a clean release. It's alot like painting a car. Most all of the end results come from a good prep. Keep at it.

Timing of your layer applications is important to get proper crosslinking of the epoxy polymers. You will have to sand any layer that has gone too long before applying the next. The parts that you build mold over have to be finished smoother than regular primer, fully cured , color sanded and polished should let go of the mold and it's release agents better.

The job of primer is to bond to surfaced and then allow other paints and top coats to bond to it. Primer is not the right product to try and pull a mold from as it is designed to stick to surfaces very well. You need to paint the parts with a clear coat, allow that to cure properly and then pollish the clear coat to a high, smooth shine. Then dozens of coats of release wax. I would also suggest you vaccume form the mold and parts. Also when you come to release the mold, try a few blasts of compressed air into the gaps and it can sometimes separate the plug from the mold.

How many parts are you going to pull from each mold? If it is one and done or maybe just two or three, that first mold would probably have worked if you fixed it. I have never had good luck with PVA but Carnuaba wax seems to work well, especially over a very smooth surface like clear packing tape. Maybe a cheap vinyl wrap with Carnuaba wax on your plug would work? When you take your part out of the mold, I would first grab one side flange with a long clamp made of scrap 2x4, grab the other end with a similar clamp and then twist. The mold should flex more than the plug which will release the corners and work it's way in toward the center. You will probably have to repair most molds because Chevy C10 panels were made for stamping, not composite molding. The release angles aren't right. You will probably need to do repairs after you pull out each new part. I know some molds are good for production but I've never seen one. I would probably count on repairing every new mold, scuffing it, painting it and buffing out the surface to get rid of orange peel and create a surface that can release. One mold I worked with a chunk fell out but it wasn't an area that needed to look nice so after filling it we patched over the filler with clear packing tape. When the next part came out, the packing tape area had the best surface finish of the whole mold...

I thought mold release was water soluble so all you had to do was get that primer area wet and scrub it off right??? If you don’t have any Ive used that stuff and it works awesome

Are you going to try to keep the lines on the carbon fiber from one panel to the next lined up

Paint parts with an epoxy flooring clear it will seal the part.stops the solvent penetration

1) you cant make a high temp mold without putting it into a high temp oven to cure it 2) curing in the oven will ensure a better release , think bout it , if the mold isnt 100% fully cured it will still stick to the plug 3) 2k the mold as everyone has mentioned 4) keep going , its just school fees ;)

If you use pva release film, you'll be less likely to get primer bonding to the gel coat,

The mold is not a total failure, yes it has problems but I would have fixed the mold using body filler. When applying your fibre glass use a roller preferably a needle type or a hard roller and stiff brush to thoroughly work in the epoxy. Your tail gate should be painted and polished to a gloss finish for best mold release. The Primer on its own is too porous as it is intended for paint to bond on to. Yes you are learning but this is costly mistakes to make , It is unfortunate you didn’t Google or search KZbin, I can guarantee there are expert videos that detail the process. Anyway keep going you will get a good outcome to be proud of. By the way just found your channel, the truck is so great already. My grandfather had the full size long WB, it is cool to see what you have done to make it so much better.

Does spray PVA release film not work with this type of gel coat? I would think that would work great on top of the wipe on stuff you are using.

Primer is meant to have a tooth that grabs the paint so I see how it’d grab epoxy. Needs a slick layer of clear coat, possibly buffed and polished

Could it be easier to soak the fiberglass in the resin before putting it on the panel maybe?

That's rough bud. I didn't have the same problem, but similar. I made split molds 3.5 years ago for my motorcycle. I didn't run into the paint issue, but did with the gel coat pealing from my flange area in some spots. I used the exact same liquids products as you, minus the aluminum epoxy. Same brands, just smaller quantity. I think you're applying the mold sealer, and release agent correctly. Nothing you said, and showed, how to apply it appeared incorrect. However, as some have mentioned. I think it's the paint that is causing you problems., And this I had an issue with on another, and much smaller motorcycle part that I started with. This paint was aerosol, and I found that you cannot use gel coat, epoxy, with aerosol. I've heard it elsewhere that you have to have a base layer down, or clearcoat. I believe that leaving it primer alone is problematic. Looks like a great project. Oh, not sure if you know this already. If you're going to use the molds right away after making them, you should apply that mold sealer onto the molds before hand. Molds that haven't had a month or two to sit, tend to not seal as well. Unless the baking changes that.
