PVA or Wax? PVA is good if you forget to put wax in the mix, but I would just let the wax do its thing. If mixed in the proper ratios the wax alone will work fine.
Once you spray with the Duratec you'll never look back. It solves so many common gelcoat problems: fisheye, orange peel, pinair, makes the surface less porous, etc. Its great stuff.
Hope that helps!
I've had opacity problems when using the duratec though...it's clear and it dilutes the solids in the gelcoat....although I do admit I've never had a curing issue when using it.
