Just a thought from my first truck-building experience. If you plan to use spray in bedliner, do it before you paint the body. I got my tub out of the body shop a couple weeks ago (after 4 months) and took it directly to the LineX guys. I lined the entire floor and bed walls. Talked the guys into shooting a charcoal color and it looks great with the new blue paint. Here's the problem....the liner goes on hot (chemical reaction) and they have to use a special masking tape with wire in it to prevent the tape from melting. They also use real sticky tape. When they lifted it, some paint came with it along the bed rails at the topper bolt holes. I'll get it fixed, but it would have been much easier to mask the bed at the body shop because the bedliner surely will not lift off with tape!
