They do a truck bed liner for applying over the POR 15----But anyone see the warning they give with it And its pictured with just a spray gun and a pair of gloves http://www.por15.com/POW-R-LINER-KIT/productinfo/PLBK/
Por15 is the best, we did a salt spray test at work on it and other similar direct to rust paints and sealers it was v good.
