Well I would highly suggest ordering durabek on line and not using the cheaper shit from the parts store. They have 18 color's and also you can get the rubber particles in a number of color's as well. I did mine prob about five years back and still looks bad ass!! Note:: you need the durabek 18 though as that's only one made with a uv protectant . Ok the stuff comes in gallons or quarts. I would just buy a gallon myself. Cost me about $120 I think. They have rollers u can buy from them if u want to roll it on, also can be applied with a brush, or you can also spray it with a gun. I did a little of all with mine and I can not tell the difference anywhere on my rig. Highly suggested product!! I chose green outside and then tan and black on interior. Good luck and any more questions feel free to ask!!
