A film company has been in town this week and I've been renting them props; cars, motorcycles, ATVs, kayaks.. you name it. I'm running out of stuff! Anyway, I need to change the color of a couple of things, they don't care about gloss. I was going to use cheap rattle can and wipe it off with thinner but I see they actually make water soluble spray paint, washes off with water. Imagine the fun you could have painting your pal's rod while he's not looking. Actually could be useful for mock up work. Here's a link, like to find it locally though. http://www.parkinchemical.com/
They use water soluble rattle can paint here in the desert, spray on top of your car's paintwork to protect it from getting sand blasted during the sand storms.
