Back in my body shop days, another painter and I sprayed 5 gallons of John Deere green Imron on a huge bush hog for the local forestry service. We sprayed non-stop almost all day. Couldn't hardly run the stuff if you tried; very forgiving paint and easy to mix & spray... My only other experience with the stuff was a dark blue metallic van that had previously been painted with it. It got a ding in one front corner and I had to repair it and spot in the paint. Yeah, right! Imron does not spot & blend well and as for buffing.., I think concrete would probably buff easier. It IS some durable stuff, though. Our local DuPont dealer doesn't carry the stuff any more and I thought it had been discontinued.

I also sprayed some Ditzler Durethane several years ago; it was great stuff for hotrod frames, boats, boat trailers, and stock cars. By the time you were finished spraying the average frame or trailer, it was difficult to walk around in the booth because your shoes would stick to the floor. It was some really tough, chip resistant stuff. You could paint a panel with it, let it dry overnight, and then beat the panel to a pulp and the paint would not chip! We painted a stock car with it once and tire marks would just wipe off with mineral spirits! Unfortunately, the stuff was expensive and deadly hazardous to your health. I don't think it's available any more, at least not here in Florida...
