i have acquired an original one design which i use to sail many years ago. they are made form polyethylene which is hard to repair once cracked.
apart form a 3 inch crack in the underside everything is complete- hardly been used
what is best way to repair crack - plastic welding sounds good but doesn't seem to last - any suggestions ?
i was actually thinking of putting epoxy or sikaflex in small air bubble then Sikaflex or glue a a thin sheet of aluminium ( or plastic) as patch - it would be proud but hopefully the plate would stop the plastic from cracking ?
