I don't have a roof rack but I strap stuff on my roof all the time so sadly it's gotten pretty scratched up, so think it's a good idea to get it bedlined (plus I thought it looked really good)

want to do it myself and I don't want it super bumpy, I don't have a air compressor but I could get a hold of one if it is better, so just wanted to see who's done it (to any body panel I guess) and what bedliner they used and how they put it on, pictures would help tons!

 

raptor bed liner comes with a sprayer and its not super bumpy like the roll on kinds can be.The rest of the brands you can spray but you gotta use a undercoating spray gun to use them.
