Don't let me denigrate what you've done, but that car is in *very* good shape compared to the floors of many Amazons. If that's your "worst" you are well ahead of the game.

One warning about sealing rust with POR15 (I've used a lot of it myself). On floors, you could still be rusting out under the body between the undercoating and the steel. The photo of the zombie 1800ES I posted earlier was just such a car. It just looked like surface rust from the inside until I poked around with a screwdriver and discovered that the undercoating was the only thing holding the floor and undercarriage together.

I recently disassembled a 1965 "california car" where the interior had been heavily preserved with POR15. It looked really good, however the rust was still causing bubbles to form through the POR.

I'm just saying that you need to treat both sides of the metal to truly stop the rust. This entails scraping off some of the undercoating (which we usually avoid).

Otherwise that car looks really nice. I love the whitewalls.
