Crazy?????

so i was thinking instead of spending all that money on dynamate so the door does not rattle. why not get a can of that expandable foam an but a layer at the bottom of inside door, you know reach down in the speaker hole and but it down there. it would force the two peaces of metal away from each other and not raddle. what do you think

Expandable foam is used to cure rattles but I would still put some sound deadening on the doors. Check out RAAMAT. It works pretty well and has a good price.

If you want the best of the best check out Second Skin.

I wouldn't fill the door with foam, especially the bottom.

Water won't be able to make its way out of the door if sealed, then you know what happens when water gets stucks somewhere.

Rust, corrosion, etc.

I would say that all the bumps from everyday driving would eventually break some of that stuff free and you would get more rattles. That sound deadening mat works really well as far as outside noise goes. I'm still having trouble with "spot rattles" just cause of the way the doors are made. best of luck.
