What is the best way to add a silicone bow bumper boat?
A The only material we have found that will bond the bumper is silicone sealant as sold by plumbers’ merchants for sealing around work surfaces, pipes and tiles. The correct one to use is the one that smells strongly of acetic acid (vinegar). Choose the clear version. No other types will work. Clean the aft face of the bumper and the area of bow that you will apply the bumper to using acetone or alcohol. Add masking tape around the area of hull that will have the bumper bonded to it. Allow the solvent to dry and apply a thick film of the sealant to the back of the bumper and a thinner film to the bow of the boat. Push the bumper onto the hull and carefully clean off the excess sealant. When the sealant has cured (leave for at least half a day) you will be able to peel off the masking tape.
