Thread: Oxidised fibreglass boat

Right I've tried 3 products saying they remove Oxidation . My last effort 3 hrs of "wax on ,wax off " would have made Mr Miyagi proud . Washed it & better but still dull . Any recommendations . Should I visit a panel beater supplier . Im thinking real course cutters ? Can I cut through the gell coat and damage it ? . Thanks in advance Munsey
