I left my calipers and pads right on the truck. I just taped them up real good. I used red engine paint in a rattle can. The next time I do it, I will brush it on with caliper paint. Like someone said, the color does change slightly over time. If you use and wheel cleaner, like Eagle1 A2Z, like I do once a month or so, be VERY careful NOT to spray it on the calipers. It will change the color and possibly leave spots on them. Don't ask how I found out.
