Car: 1988 5000CSTQ
I'm in the middle of a sound-deadening orgy. At the moment I've removed all factory trunk liner and carpet and have been applying Dynamat Xtreme (with excellent road test results so far).
The car's spare wheel well is a single molded plastic (polystyrene?) piece, above which a carpeted and sound-deadened (with foam) fiberboard "floor" fits. I think that this is a fairly standard Audi sedan layout.
Question: What material is sensible for quieting this plastic molding? I'm thinking of gluing 1/4" closed-cell foam sheet to its inside surface (rather than Dynamat Xtreme). Any BTDT or suggestions?
TIA.
