Hi
Is there an easy way to remove the mother of all ugly bias strips from the bottom of my boat
without doing damage to the original cloth and epoxy? It was supposed to be a protection
strip but it is wavy, (zig zags all over the place ) turned out cloudy and has a thick thread
showing. Maybe I could sand it into shape paint it black and pretend that it's a carbon skid
plate. Any suggestions besides "Don't do it in the first place" ?

If this strip was recently applied you might be able to remove it by heating it with a hot-air gun and peeling it off. Pull horizontally so it doesn't lift the original glass off the hull. Try to judge how hot it has to be to come off without damaging the other glass. The only other way I know of would be to scrape and sand. It might be easier to scrape the lumps, sand, do any necessary fill coats, sand and paint.
Got any pics of this horror? :rolling eyes

Roscoe,
This is probably a strange suggestion from a hand tool guy, but maybe a GENTLE pass or two with a rough grit belt sander? I'd work the sander at 90 degrees to the strip, kind of tilting it up on one edge and holding it so that it only gently touched the glass. Pass it over the bias strip a foot or so at a time, moving along the strips length with the sander perpendicular to it. Wear a mask.

Cheers guys
Thanks for the suggestions. I am working on the gunnels and decks at the moment so won't be able to get at the bottom for a while. I'll try scrapeing a bit first to see how hard it is to feather the edges and go on from there. On the plus side, with so much ballast in the strip it's going to be hard to tip over.
Thanks again

Hi
Back again. Well I took your advice and scraped, belt sanded and RO sanded. When I wet the surface now there is still a few tiny white spots maybe it needs more sanding but it is a lot better than it was.
Is what I see when the hull is wet the way it will turn out when I coat with epoxy?
Is there a way to test the strength of the hull before launching? I'm a bit nervous as I may have sanded into the cloth when I did my first sanding of the hull. I'm thinking of glassing the outside with 4oz cloth to be sure. Is there a trick or technique in being able to see the cloth?
( There certainly would be if it's not there )
