Anybody ever try this? I don't know of any aftermarket heavy build coating that can duplicate the thickness or texture of the factory undercoating/sound deadener. I need to spray the quarters (inside trunk area) on my '70 Cuda as the orig. coating is falling off & losing it's adhesion after 40 years. Plus, after the car is finished, I'm going to spray the rear tubs & front fenderwells like factory. I'll have a pro do this with all the right application equipment so I get a heavy buildup.

What do you guys think? Also, can this stuff be painted over after it cures?
