per and epoxy compatability

I’ve read multiple posts of people infusing epoxy behind a sprayed layer of clear gel coat. Then when I made an order from uscomposites I got a call that epoxy and per shouldn’t be used together. So what advice do I follow?

You can use Epoxy on a PER coating as Epoxy sticks to everything…but don’t put PER onto Epoxy surface as then it doesn’t.

Yeah thats what I thought. Thanks for the reassurance.

I infuse a lot of flat sheets with PER gel coat and Epoxy resin. It does get a lot of surface on it and needs wetsanded pretty good.
