Bed Liner time. The cab is all enclosed and the rig is being built to handle full-time living.
The Duplicolor worked well:
Waterbased-Polyurethane. Voc content is ~130g/l IIRC, hardly reeks opening up the can.
Thin, watery, and clumpy even mixed. I wouldn't bother rolling this type.
Second Lizard Skin imitation layer. "Heat control"
Ceramic Microspheres from the glass supply mixed around 1:1 and spattered with a 3mil gun.
Thick spatter on door/body skins and exhaust side floor pan. Full coat to follow.
