I wouldn't do it either. Just pull it down, if you are THAT determined, as far as it will go (I promised myself to never do that again) and get it blasted. I also wouldn't let it sit in the weather. Once mine came back from the blaster, I painted it that next day. It will stick fine. If you only plan to put POR on it, don't leave it in the sunlight too long, it will colorfast. I topcoated mine, 30 minutes after the last POR application, with Gloss Black enamel.
