I loved doing this project, and the results transformed my truck. I read up a lot about it before starting and thought a lot of stuff on YouTube said it can be done with 2 bottles of raptor liner, personally I don't think that's possible. I used a bottles and would even use 10 if I do this project again. Don't be cheap. Order extra roller brushes and paint tray liners, they dry rock solid fairly quickly. Once applied and baked on by the sun, it really is tough as nails. I gouged the truck with a metal hook and not a mark.
