Before anyone tells me you dont need primer to use Duratex, I know. I was going to paint my speakers but I cant have a gloss finish because its for a rear projector home theater. The speakers already have the Zinsser Shellac based primer on them. Is there an issue with adhesion?

I emailed acrytech but didnt get a response.

I already bought the duratex so its an issue of going over it with automotive primer or just going over the Zinsser. The Zinsser is really durable and scratch resistant. Its an impressive product.
