How to use plastic patch on boat?
Commonly used in boats like kayaks, along with plastic barrels or tubs, plastic patches act somewhat like a bandage that can cover a surface that has holes or cracks. Using plastic patches requires one to heat the patches in order to soften them up for application. Once applied, it only needs time to cool down to stick on the broken surface, and the repair is done. It is worth noting that this method uses heating materials that can be dangerous if not used properly and that the same kind of plastic must be used to ensure that the patch would stick more effectively.
