Duplicolor is a good product, I've used it several times. You control the texture (if you're spraying) by how far you hold the gun from the surface. Nearer gives a smoother coat, I've gone as far as four or five coats, doesn't really noticeably change the product, other than to add a few mils. Definitely controls sound deadening and has insulation factor. You'll never get it as thick as, say, rhinoliner brand (up to a quarter inch), but it works well for interior application, or on the walls of a pickup bed with a bed mat. Haven't used it in the bottom of a pickup bed tho. I'd stay away from this or any bed liner product if you're ultimately looking at retail, because everyone assumes you're hiding something. A good product at a very nice price.
