Ray,
I have allways used the Ecklers Gelcoat, which has the wax in it. I allways spray the Gelcoat out in one process. If you need to spray another coat with this type of gelcoat after it has started to cure, you would need to sand off the waxy layer that forms on the top. I use PVA and conventional gelcoat for making fiberglass parts from molds, but have never used it for curing the gelcoat after spraying. If evercoat's system uses this process, then I would probably consider that system. Removing the wax on Ecklers material has allways been the great pain in using it. The real advantage of PVA is that it is completely soluable in water, and can be removed with a nice, warm water scrubbing. I may have to look at Evercoat's Gelcoat on my next car! I am just creature of habbit, and have stuck with the Ecklers product because it has worked, but If I could get comparable results with the Evercoat product, I would use it in a minute. I have used their primer/surfacers and fillers for years, and have never had a bad result.
One little peice of advice, When you are spraying any of the polyester products, do not spray it from any gun that would break your heart to throw away! I had some Evercoat Featherfill set up in a great Binks #7 gun several years ago, that I had owned for years and ruined the gun. In real hot weather, or if you catalyze it too heavy, the stuff can set up in a flash.
I was spraying along, and saw the gun sputter a couple of times and spit some globs of surfacer. By the time I took my respirator off and opened up the gun, it was too late to save it. I now use a cheap Home Depot Cambell Hussfeild gun to shoot all polyester products. It aint going to break my heart to throw a $35 gun in the trash!
