i have a 1987 Honda hurricane cbr 1000 recently i had hit a speed bump going about 5 mph after that my bike has been sounding really rugged?
If they are painted yes, and that sealer is fine. However if it isn't painted I don't.bother sealing especially if it's going into a resin piece.
If its Broken its broken don't try and repair it. Go buy a new one they are not that expensive.
