I'v sprayed bedliner for 12 years and it is a VERY cool product. I'm planning on spraying my new build ( 12 x 7 ), roof, sides, everything. It will be white with a UV top coat. Here's the scoop. There are 3 type of bedliner material.
1) low pressure (Rhino, Vortex and Tuff liners) they have a softer, marbled surface. sprays a little thicker than other liners because is softer.
2) High pressure/ high temp liners (Line-x, Ameriguard, Stone liner ect. Harder material, tighter pattern on the surface, no runs or drips. can be sprayed thinner.
3) Roll on stuff ( Can-O-Liner) do it yourself product. small areas GREAT, big areas CRAP. I use it all the time for small jobs.
This stuff can be HEAVY. Make sure that the surface is as smooth as if your going to paint it. This way you dont have to put more material on the cover holes and bumps. This will drive up the cost and weight. With the hot,high temp system I have all projects can be color matched (base coat color close, top coat OEM colors) make sure they use a UV product top coat.
I'v sprayed the roof of a museum quality 1930's trailer and it turned out great. I'll have mine done in a month or two and will take alot of photo's as it gets sprayed.
