Undercoating?

3M rubberized only . put on one coat let set up and apply a second coat. The first coat always gets pin holes when it sets up. If you have a bright paint under it you will see specs of color under a light.

I have had cars come here for repairs after they applied bed liner for under coating and on interior floors. I send them on their way.

Also the sound deaden er aluminum covered foam. I won't weld or do repairs on a car with it on. Dave put it on his Valiant floor. Ask him how hard it was to remove so we could install a front clip. when that stuff starts burning its hard to put out.

So are you saving the car? Or destroying its chance to be saved in the future. It would be like bringing me a flat tire to repair filled with fix-a-flat . I won't even put it on my tire machine.
