I've heard good reviews on the Pbblaster undercoating spray. I also have some used motor oil i could make use of in the right places but Would likely mix it with something stickier. Ive never done any diy undercoating but I have had it done a few times since buying the vehicle. Just wondered what other folks are doing. Also tips on protection when applying sprays. Get a face shield, filter masks? Lay plastic or old tarps under to catch drips?</p></blockquote><p></p>
