Re: [Cal_Boats] Coating on Hull Gelcoat

I don't think it was applied during manufacture, any coating applied at that time would have worn (or been buffed) off by now (well ,except the mold release wax that can stay on for ever seemingly... and must be removed prior to painting). My guess is that the coating is one of the "Acrylic" boat polishes, like POLYGLOW. They eventually begin to look blotchy if not periodically removed and reapplied.

All I know about boat production is that they first spray a release agent on the mold, before spraying the gel coat, followed by polyester resin and resin saturated glass cloth. The release agent both seals the gel coat from air which will inhibit the curing of the gel coat, and allows the finished hull to come free of the mold once the hull has cured. The release agent should be a waxy very long chain alchol molecule probably not much different from what's used in some cosmetics.If it's really still there after all this time you could try simple green, or some mechanics hand cleanser if you want to get really aggressive. But, assuming it's just oxidized gel coat, that is typically removed by a minimally aggressive rubbing compound, followed by polish n' wax. But I see, um, uh, Captain DEmO has already given you the cook book and what to do to make your hull lookin' like new, and I like what Rod says about deteriorated polishing compound becoming cloudy over time. Yah cood get really edgewkated bein' on this here CalBoatList. Gawrsh! I probably have the hoggyest looking boat out there at the starting line, (with brown oxidized metal stains below me chain plates, and black gunky smears from rotting vinyl bumpers), but being on board, I don't have to look at my boat. I can just look at everyone else's boat hull and sails and revel in the delusion that mine looks just as spiffy!Jerry of Shpritz On Wednesday, October 15, 2014 9:20 PM, "rj… [at] juno.com [Cal_Boats]" <Ca… [at] yahoogroups.com> wrote: I don't think it was applied during manufacture, any coating applied at that time would have worn (or been buffed) off by now (well ,except the mold release wax that can stay on for ever seemingly... and must be removed prior to painting).My guess is that the coating is one of the "Acrylic" boat polishes, like POLYGLOW.
