I am using 3M role lock, I'm using a course sanding pad rather than the scotch brite type pad. Thanks for the tips, I was trying to get the bed to look new so I did not want to do a lap patch. If I had the room I would tack a piece undernieth to help support my patch and disipate the heat. Unfortunately where I am working is just above the fuel tank and the frame runs undernieth as well. If I cant get it done with the gas attachment on my machine, I guess I will have to buy a oxy/acet torch.(new toy <img src="/forums/images/graemlins/smile.gif" alt="" />) I am cutting out the piece that I burnt holes in and starting over. Can't wait for my gas attachment to come in.
