I know everyones using that dynomat at BB and CC is it the best route? how can i stop my gas tank from rattling and the inside back top braking light. without using a sock or something heh. And also my trunk
quite a few methods. dynamat, or similar other brands. expanding spray foam spray-in liners that black putty goop they use to seal windshields into cars (its called "dum-dum") which is great for sticking a license plate down and such when it rattles. also good for plastics. stuff like that.
