Gel coat hardening spottily-Help
I rolled out a 6' x 4' panel with waxed gelcoat. It failed to harden
in spots.
The gelcoat went on a plywood panel which had been prepared with mat
and 8 oz. resin. The resin hardened and was leveled through sanding
through 220.
The waxed gelcoat was prepared with a slight addition of a brown
coloring agent and was catalyzed at 9 cc per qt. It was applied with
a new roller. Most of it hardened beautifully but there are spots
which failed to harden.
QUESTION: Does anyone know what might have gone wrong? Could the
unhardened spots be hardened by spraying on a film of MEKP or could
they be coated with PVA or wax?
All suggestions greatly appreciated.
