The gelcoat is definitely hard but:
- despite 6 passes of easylease and 6 passes of wax in the mold, it has adhered to the part (can be removed by chipping carefully with a scalpel)
- the reinforcement on the cured gelcoat, laid to make the mold, almost did not adhere to the gelcoat. The explanation for this is for sure, as Hanaldo said, the sensitivity of epoxy gelcoat to its overcoat window.
