If you are hoping that after applying this it will look like it was sprayed on then don’t purchase it. If you are looking for something that appears that it will withstand a nuclear blast then look no further. I did apply it quite heavily. My truck bed is only 5ft and two coats used the entire can. Forget the rollers and apply it with a brush. Purchase at least 6 of the cheap disposable ones. You will need them for touch ups. Think of this DYI as you would with any painting project. The prep work is where it matters. Sanding pads (the scotch bright type) are better than sandpaper for roughing up the surface. Wear gloves and a respirator, not a dust mask. The fumes are abundant. A mixing paddle on a drill is preferable to a stir stick. My biggest mistake was applying the first coat too heavily. The medium (liquid part) can pool away from the texturing if you don’t spread it evenly. My first coat took a lot longer to dry than stated on the can and it’s easy to miss the direction about NOT letting the first coat fully dry before applying second coat along taped bounderies and then removing the tape before that dries.My vehicle is a work truck so I was looking for protection over aesthetics and I think I succeeded with that. Also saved myself a butt load of money over a professional installation.
