Has anyone used dynamat on their doors? I took the panels off today and couldn't believe how much the doors rattle. I've read about a guy using some generic sound mat to replace the vapor barrier in a Toyota MR2, but I'd rather use dynamat instead. Anyone know where to apply the dynamat? I don't want to blanket the doors with it, I'd like to do both doors using a $20 roll (about 3-4 sq. ft). Thanks!
