I was wondering if anyone has had similar issues with the uni-mould tooling gelcoat not curing after 3+ days. The gelcoat has been mixed with the recommended 2% MEKP hardener along with 2% wax additive and has been brushed onto MDF board that has been machined to the shape of half an aerofoil. I have attempted three different moulds with two different results. One having looked like it was hardened and ready for polishing however under the wax layer the gelcoat was still meallable, and the other result being that the gelcoat was still practically as it was applied. Any help on this would be greatly appreciated.
