Gelcoat is not a finishing coat; for fibreglass mould making, 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.

What is the shelf life of Catalyst?

The shelf life of Catalyst is approximately 6 months. It is important that the catalyst is stored in its original packaging in a cool, dry location away from sunlight. As Catalyst is an extremely flammable chemical, it is important to refer to MSDS and TDS sheets before use.

I'm interested in making some fibreglass moulds, would I be able to use a release agent and then the top coat first?

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.
