epoxy paint for fiberglass gel coat


I am in the process of making a mold for a ducting that I would like to easily reproduce using fiberglass. I would use the lost foam method, but since I want to reproduce it this is out of the question. I read a post that said that Epoxy paint is better for this rather than using gel coat.

What type of epoxy paint do I use?? Is this available from the local HW stores like loews, Home depot?? I will be using a Balsa plug that has been sanded and prepped for the paint. or should I just use wax? and if so where can I pick this up locally rather than having to order it??

any suggestions would be great

What type of finish do you want the part to have? If the finish does not need to be REALLY smooth, you can wet sand the primer, wax it and it will do fine. If you want the REALLY smooth finish, use epoxy paint, well cured, then wet sand to the finish you desire. Usually 600 grit will do, but you can go much finer if you need or want to. One thing good to remember about fiberglass molding is that the smoother th finish on the mold, the easier the part comes out. This also save the mold, so if you are going to produce any quantity of parts, the smoother the better. The spray can epoxy available at HD, etc., will work, just not quite as well as two part. For plug painting, it should be fine.

Good luck,

It is for a EDF ducting so smoothness is very important. Who would have the 2 part online??

Thanks

I'll second the use of klasskote. The stuff works great. It's what I use when painting in the mold for making fuselages and wings.

I get it from www.klasskote.com. It is a two-part epoxy paint. Home Despot and the like don't carry things like that.
