I've seen this a few times. I might do the bed of my truck just to cover all the scrapes and rust.

 

I've been considering doing this to my truck too. My car can look pretty - the truck just needs to get me and whatever I'm hauling where I need it to get to.

Think it would work changing from red to grey? Likely just more coats, right?

 

Hi, so does the Rust-Oleum color act as the paint color for the truck?
