glass on fins... at what stage?

General Discussion

Crap… I overlooked an important detail. I just did the lam top and bottom layup. Gonna get ready to do a sanding coat. Goal is to work up to a nice gloss finish. At some point I changed my mind to go with glass on fins, and not installing boxes… and I’ve never done this. So I’m trying to figure out at what stage to glass the fins on?! Before sanding coat, after sanding coat… after gloss coat? I searched but couldn’t find a straight answer, please help.

Thanks in advance,

Tyson

You tack your glass-ons onto the laminated bottom with lam resin. Apply your roving and patches, let gell, trim excess glass off around the edge of the fins and shoot your sanding coat.

Yep…

…and I’ll hit my sanded lap with some of that fin resin, too, then sand it all down nicey-nice before the hotcoat.

You can hotcoat the deck first so you can grind the drips at the same time you feather the fin patches.

I tack the fins on with a dab of hot glue to hold them in place while I glass them into place after the lam and before the hot coat. You can do it after the hot coat. Just sand the area very well. Mike

Hey thanks guys, I wasn’t sure if to put on the lam coat or sand coat. Everything worked out perfect. Will have pics to post soon.

Um, close but not quite right. You can’t tack on or lay up the fins until the drips are ground and the laps feathered. Think about it. So, hotcoat the deck first, then grind laps/drips, then tack on fins and lay them up. If you want to feather the patches, do it before hotcoating the whole bottom.

Let’s try not to steer these guys wrong here, eh?

It told you, no more glassing for you, Bait, just stick to shaping you Trogg.
