Isn't That the Truth!I have found a better gelcoat result over poly or vinyl than I got with gelcoat over epoxy.
I'll keep that in mind, the next time I pull my 290WA into my basement to work on glass issues.Not saying polyester is bad but epoxy is easier to work with. And if your working in the attached garage or basement your better half won't be smelling fumes. Epoxy is also more resistant to water absorption. I hear that there is a conversion coat to adhere poly to epoxy. All gelcoat is polyester. Here is a good supplier of resins but like everything lately some are out of stock. http://www.uscomposites.com/
