I want to run by some plans for my car to the experts and let you guys weigh in on what you think. First of all it's a 66 lemans, convertible 4 speed. Body is now completely stripped and I'm sending it off the sandblaster, they also happen to be the powder coat place. I was thinking about having the bottom of the car powder coated, interior, and the frame. I can't decide between that and POR15. The POR15 vs powder seems to be a common discussion but the discussion is usually based on what is more work and since it is already taken apart that isn't really an issue for me. I have almost an obsession for making things "bulletproof." I want to be able to put a salt water sprinkler under the car overnight when it's park and not have to worry about it for 50 years (slight exaggeration but you get the idea). So what is the more durable coating for that stuff? I'm getting the hood and truck acid dipped because the blasting won't get in the inside parts where I hear rust rolling around. But at $2500 I'm going to opt for sandblasting instead of dipping the whole car. I even seriously considered powder coating the whole car, then putting normal paint over that. But enough people talked me out of that idea. Thanks again for all your help on my ongoing restore job.
