Since local gelcoat prices for me are crazy high ($75/gallon at the cheapest), I bought a quart of titanium dioxide pigment to mix with my iso resin.
Last night I mixed a pint of resin with 3 oz of pigment to achieve an opaque white color. I then added some milled fiber for thickness. My thought is that the fiber will make the gelcoat less likely to crack as opposed to using fumed silica or another powder thickener. This coat is going in the ski locker, so a beautiful finish doesn't matter to me. The pint didn't go that far, but worked well and looks fine! (To me lol)
My problem is that, for the final coat, no local stores carry any wax additive for the gel. I've been reading of people using things like wax paper, PVA, etc to help the gelcoat cure non-tacky. But I have an idea....
Could I simply use some Rustoleum clear gloss enamel spray paint over the gelcoat? It just may even look good. If this is a bad idea, someone please tell me before I try it.
