I finaly got around to doing the hood and rockers with Monstaliner do-it-yourself roll-on truck bed liner outperforms Herculiner Bed Liner, Duplicolor and Rustoleum Road Warrior. So far, I am much more impressed with the monstaliner than I have been with Duplicolor and herculiner. I have used the duplicolor roll on and the duplicolor and the herculiner spray on bed-liners with limited success. The spray on liners wore through too easily (canoe tie down straps were able to wear though the spray on bed-liners in a 2 day camping trip). This material seems to roll on much thicker and with a better consistency than I have seen on the other aftermarket liners. I was tempted to use a undercoating gun to spray it on, but Eric at Monstaliner suggested that I roll it on and see how it turns out. I basically followed the directions in the kit. Here is what comes in the gallon kit. You get the catalyst, a slightly unfilled gallon of the bed-liner (you cannot have a full gallon if you want to add the quart of catalyst). my kit did not come with the roller pan so that is from Ace Hardware. Everything else came with the kit.. One you add the catalyst to the gallon, you use the mixing stirrer on a drill to make sure the catalyst is evenly distributed in the gal of bedliner material. Prep was fairly easy. Tape off the edge you want and then use the sanding pad that comes in the kit to rough up the surface that you are going to cover.
