Thanks, everyone for the input. Actually I am mostly concerned about adhesion. I decided to "ere on the side of caution". I've already decided to go with a product that I've used in the past, called "Bulldog". It will be on there today.

The "starring" problem is an old one on street rods, especially for the years when I used lacquer paints. I started undercoating fenders to prevent that. I'm sure Rhinoliner would help in a similar fashion, though urethanes aren't as bad for this.
