Lumpy Gel Coat: Recoverable?
Few years back, a surf ski developed cosmetic delams in the gel
coat around the cockpit area. The builder sent me a half pint of polyester resin pre-mixed with yellow pigment and, I guess, wax. Stuff worked. But now I want to finish a ding repair and, upon opening the can of gel coat, find that it's gone all lumpy. If I stir it long enough, some of the lumps smooth out, but I still can't get it to where it will flow properly upon application. Is there any hope for this stuff (thinning agents? extreme agitation - as in a paint store's mechanical shaker? something else?) Or should I try to get some fresh resin/pigment? If when I do get some fresh stuff, it seems more logical to me to ask for the pigment, resin, and wax as separate items and then mix them when needed. Am I on the right track with the separate ingredients approach? -- PeteCresswell |

Lumpy Gel Coat: Recoverable?
A little heat might work. I've had good luck submerging the can in a
bucket of hot water. On Mon, 25 May 2009 15:04:54 -0400, "(PeteCresswell)" wrote: Few years back, a surf ski developed cosmetic delams in the gel coat around the cockpit area.

You can buy a pint of white gelcoat and get a little pigment kit from
Evercoat via eBay. Mix your own. the shelf life of gelcaot is pretty short. I keeep some mixed for my little boat in the frige and it has been ok for a year now but I'm sure that's pushing it. I don't mix wax in with the gelcoat. I spray PVA over it. I keep it in the beer frige in the shop, not in the house.

Per Pirateer guy:
I don't mix wax in with the gelcoat. I spray PVA over it. Polyvinyl Acetate? -- PeteCresswell |
