Re: Gel Coating Vinyl Ester
Vinylester is just a more resilient, and a bit more water resistant form of polyester resin. A lot of builders …I think even SeaCraft …. Use it today
Isothalic(sp?) based gel coat is what I have used in the past over vinylester (Isothalic is just a higher grade of poly resin)
They even make a vinylester based gel coat for high wear areas like a hull bottom. Vinyl is a step above Iso ...and cost more too.. Remember the gelcoats are really just pigmented resins.
