I was just curious what everyone prefers to use:
I am a big System 3 epoxy fan, as I used it on my two powerboats, and it was great resin. Their paints are also excellent, but quite expensive, and overkill for a paddlecraft.
I also like West Marine Epoxy, but it does create a lot of amine blush, and it is super expensive.
I'm currently using US Composites 635 resin, and it is pretty good, though a little thick for my preference.
As for Paint, I know you can use just about anything, but some applies and lasts better than others. I'm intrigued by Ben Moore M43/44 acrylic epoxy paint...supposed to be very abrasion resistant and chemical resistant, and it thins and cleans up with water instead of thinner, much like the expensive S3 paint I used on my powerskiff.
I'm still fishing for paint ideas. If you go to a typical paint store, it blows their minds when you want to use a paint for something other than a home application. They get all excited about the fact that that application is outside of warranty. I don't care what it was meant for, but what it is capable of.
I have a lot more trouble picking out a good primer that will bond to epoxy and acrylic latex paints.
I'm a big fan of cheap woodflour as a filler. It is lighter than talc, and good for structural components, glues, and fillets. Just don't fair with it...it rolls up too easy.
I love System 3 QuickFair for fairing. It is buttery smooth and easy to mix, and sands like a dream. It isn't cheap, but it saves a ton of time.
