[QUOTE="Based, post: 8312916, member: 660638"] I did my back doors today. Put one full layer of Damp Pro on the inside of the outer skin (the part that flexes) and then I filled a good bit of the door with Great Stuff expandable foam. These doors DO NOT MOVE!!!! They used to flap like bird wings running my 4 OA 15s but now there is no flex at all. I did the same thing to my roof. Put damp pro all over it and foamed the braces and all the open spaces and the roof does still flex a little but you can't hear it at all. I'm close to being rattle free... I need to figure out what is rattling in my back wall area. You can only hear it on the outside and it only happens when the doors are closed so I'm thinking the doors transfer power to something in the back. I can't see anything on the outside that's moving so I guess it's something inside the back wall. But yeah Damp Pro + Foam ftw baby [/QUOTE]
