Well most of the high end paint coatings you are talking about are polyester based resins anyway... From the AwlGrip website: "Type: Two Component Linear Aliphatic Polyester Polyurethane"

So, AwlGrip if used can be considered a "polyester resin" and therefore is allowed by rules.

This is a ridiculous argument, get over it. Paint can and should be allowed, even for new builds.
