Some bodypanels of My CPI Hussar are broken. Now I try fix it. Panels from ABS-plast. This material is impossible fix with epoxy or polyester. First i heated cracks with soldering iron and "welded" together from both sides. I thinked only welding its not enought hard - drilled small holes around the welding and sew it up with wire. In sewing time heated wire with soldering iron to go inside plastic. After cooling I cutted welding smooth. I think its hard enought. Now its waiting filler, sandpaper and paint. Mabe somebody advises better fixing solution?
