Nice DIY
Some people have claimed that expanding foam products have popped out body lines / panels on their car. You'd have to use a whole lot to create those kind of forces. What you gain with using the foam instead of just deadener or deadener spray right away, is the foam will get into places you can't with just deadener and help prevent more rattles.
Is Great Stuff really necessary? I've heard some bad things about it.
Can't we just apply some spray, or a deadening mat and call it a day?
