What is the difference between Topcoat and Gelcoat ?

Gelcoat is not a finishing coat; it is painted onto moulds/plugs and remains tacky after it cures. Resin and Glass are generally applied on top of the Gelcoat. It forms the hard, smooth shiny surface of the finished article and is usually pigmented. It paints on easily but does not drain from vertical surfaces. Use Topcoat if a finishing paint is required.
