How do you guys carpet your cabs so you avoid messy seams? Do you precut each panel's carpet and glue it into place? Or do you wrap the whole thing (providing wide enough carpet) and have detachable tops/bottoms (which you can then hide the seams inside the body at the expense of a non-sealed design)? I haven't figure out a consistent way to carpet cleanly. As long as the front/top/sides are clear, I'm happy, but ultimately I'd like to figure out a better way to do this. Has anyone tried that spray-on stuff like you have in a truck bed? Costs? Safe?
