Imron was developed as an aircraft paint, as they don't get very many rock chips at 15,000 feet, lol. It's very hard paint that will stand up to any chemical you can throw at it. Unfortunately that hardness transfers into scratches that won't polish out, and it chips badly when it does chip. That's been my personal experience. We did use a paint on crop dusters called alumigrip(sp?), that was extremely flexible. You could spray it on a piece of sheet aluminum, and bend it over 180* without cracking the paint. I wonder if that could be sprayed on a bike? Hmmm.,,,,BD
