I might, at that.
When I worked at Wescott's Auto Restyling maintaining molds, we did NOT
use PVA as a mold release -- it's great stuff as far as being quick,
reliable and easy, but it doesn't retain the shine the way that you can
with buffed, sealed and waxed gel-coat.
We did use PVA anywhere that we needed to apply polyester to an external
surface and have it cure completely -- polyester resin doesn't cure in
the presence of the humidity in the air, but it will cure under PVA.
