Im Dynomatting everywhere inside the cab and doors, Im really trying to get it quite as possible inside the cab.
Would this be a bad idea?

Most all new cars and trucks have foam sprayed in them for noise control. You will have to get the correct stuff. The kind that does not attract moisture. If you have rust in there now don't know if its a good idea. All the new cars have corrosion protection far superior then back then.
