Re: 1981 18ft starcraft supersport
Last night I put resin on each side and twice in all edges. I am using fiberglass resin. For the first coat I used just over half the amount of hardener recommended so that it would have time to soak in. I might do one more coat all the way around or maybe just the edges before I fiberglass it.
No need, just as that 1st coat of resin starts to become tacky, roll on a 2nd layer of resin, lay on the cloth, and fully wet it out.
Too much resin can be just as bad as too little. When it's applied too thick (resin rich) becomes brittle & w/out the glass it has little to no value. Under catalized is also not ideal, when you say 1/2 the recommended amount, did you still use at least 1% MEKP? Using metric makes it much easier to accurately catalyze your resin mixes...........
This ^^^ is for polyester resin
Most tin builder's prefer the epoxy to polyester. Jig is a huge fan of epoxy
And he's right about making the new transom lamination too thick to go back thru the gap in the gunwale, and fit in that angle 'shelf' at the bottom...........
