I talked to a power coat outfit about coating my C3 and the guy suggested a teflon coating for the bottom of the deck as it makes it a snap to clean. Trouble is, it is expensive and I can just imagine my wife rapping me on the head with a wooden spoon when I hit a rock like she does when I reach for the wrong utensil to use with the teflon frying pan
I am thinking it migh be great for a while but I wonder how it would stand up to time.
About 30 years ago I painted a car with Dupont Imron paint. Well I HAD it painted but I did spray the nose hanging from a clothesline plus the engine compartment myself before installing the engine. I had a mask (useless for this stuff) but waited for a windy day and I held my breath. The folly of a mis-spent youth. I think this may have been one of the nastiest paints ever from a safety standpoint but it was the toughest paint I ever saw. I saw the car around town about 10 years ago and it looked like it was painted the day before.
