I started a second mould (Unimould system) a few days ago, and the gelcoat is not hardening as it did the first time.
The second coat's surface area seems to be 95+% hardened, however there are little patches where it hasn't. In these places the gelcoat is no longer a shiny 'gooey' fluid, it's matte and some what pliable.
Is there any way of recovering this?
Tomorrow is going to peak at 27 Deg C, could I put it in the sun and use the exotherm of the coupling coat and tooling resin coat to harden it?
