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
If the area has an old layer of Topcoat which you wish to refresh there is no need to prime the area with a product such as G4 for example. You will, however, need to sand down the area, wipe down with Acetone and reapply a new layer of Topcoat/GRP materials if required.
This depends on the type of mould you are trying to make (male or female). In this case it sounds like you need a gelcoat rather than a topcoat. Please refer to our guide on making a mould which will detail the mould making process.
