Even the sturdiest boats are known to take some dings from poor landing, misplacing a drill hole, or dropping fishing equipment. On the bright side, these scratches and gaps in the gelcoat can be repaired with good technique and patience.
Corleone Marinas take a look at the importance of a gelcoat for your vessel and explain the process of applying a DIY gelcoat.
Gelcoat is a special coating that is used to paint over the fibreglass on a boat’s hull. Gelcoat has polyester resin, epoxy, a catalyst, and other chemicals to make it protective against the elements. When combined with the fibreglass of the boat, it makes a smooth, durable surface that retards the hull from weakening in water and from ultraviolet light.
