Re: Body repair
What is the hull made out of? I would presume polyester resin, and so would use polyester, epoxy and polyester aren't compatible, so use the resin the hull was made from. <br /><br />You will need to bevel down the hull from the inside with an angle grinder and abrasive disk 3" from cut on out to each side and the ends. On the outside of the hull, put down a layer of duct tape to keep the resin from dripping through. Use a respirator when grinding the glass, safety glasses, and a set of overalls, the dust is bad for the lungs, and itches like crazy if the fibers get on your skin. Dust masks are not the same as a respirator, and don't keep all the dust out of your lungs.<br /><br />Mix up the resin and catalyst thoroughly according to the instructions, work in cooler temps, and don't put in too much catalyst, or too little. Using a disposable bristle brush, put a layer of resin on the area you ground down, then a layer of matt, then more resin to saturate the mat, then another layer of mat, then more resin, and a 3rd layer of mat with more resin to saturate. <br /><br />The second and 3rd layers of matt don't need to be the full width or the repair, say 6 wide first piece, 4" wide second and 2" wide last piece. Don't forgo grinding down the hull to a bevel as glass does not go around corners, or fill slots. <br /><br />Once the resin is hardened up, then peel the duct tape, sand the outside, fill with bondo, sand again, and paint.<br /><br />Do the job right, as a failure on the repair will result in a hull breech, and no doubt at the most inoportune time as possible.
