Undercoating...
 

A question to the pro's from another.

I really don't care too much about putting carpet in my truck so I was thinking about putting down my Boom Mat scuffing it with a red scotchbrite, spraying it with Bulldog then shooting Rubberized Undercoating over it. Given enough coats and dry time I know the undercoating I use gets rock hard. But do you think it will work fine on the Mat?
