This is what I was hoping to hear in replies. I have a friend that is pushing Por-15. I am worried about prep. I seem to remember people saying if not prepped right it will peel off in sheets. Not sure if accurate or just tall tales from web. Any experience with the Eastwood left as the topcoat? Not sure I will be applying the Raptorliner before the 48hr window and it wouldn't be in direct sunlight.

Not an old wives tale about POR15 peeling off in sheets. I sprayed the bottom of a hood for my Challenger with POR15 after using a generic metal etch on it. Same primary ingredient as the POR15 brand metal prep. Followed the instructions on the POR15 otherwise. Looked great, then had an edge come up when I was moving the hood around. Peeled off in sheets.

What you've got there is basically bare metal, I'd treat it accordingly and not use POR15 on it. @matthon has the right idea.
