Re: I have a problem on my hull. Can anyone help?
Looks like your doing a new deck too.... Have you checked the foam for water saturation? Take some core samples and see if it's wet below.... if so it will need to come out....you should check stringers and transom for rot too while your in there.
In the first pics looks like a gash of a saw cut? Both hull repairs will need to be ground down to clean glass feathering outward inside and out... you will need some csm and resin....cut csm patches small to large increasing in size an inch or so bigger then the next. On the outside tape some plastic over the hole...on the inside wash down the area with acetone and start by wetting the area with poly resin/MEKP mix....lay small patch and wet out csm then proceed with larger patches and wet out again...then take some 1708 biax cloth and cover the area with 2 layers larger then the csm.... Same thing on the outside....then grind/sand flat....mix up some resin and add glass bubbles to make a fairing compound...apply to repair sand down low. Gelcoat the outside wet sand with 800,1000,1500 and 2000 grit paper and buff out.
I had to say it
