Several years ago Dupont put out a paint here called Chrome Allusion that would change colors just by moving from one spot to another to look at it. They painted Jeff Gordon's NASCAR Cup car with it for one race and there was a Hemi here that had it, but the paint cost as much as the car. Then it went away and I think it was for legal reasons. You could have 10 people stand look at the car from a different spot and every one of them would see a different color or shade of color. I haven't seen it advertised for several years, so I guess they quit making it.
Then there is this that a member just posted on our site but I don't know how it would work out over time.
