Vinyl Roof Replacement

You can use the POR 15, but I would shoot a coat of primer while the POR 15 is still tacky. As you said, it is to slick and the adhesive won't bite into it. I have installed a dozen vinyl tops this way and have had no issues.

Excellent, thanks. You confirmed my suspicions about the POR.
BTW, used to work in Newark, N.J., in and around (Essex, Hudson and Union Counties).
