Double Noise Blocker Sound Proof Foam, 39.4 X 13.4 X 1 inch Egg Crate Foam Rubber Sound Deadening Material, Sound Dampening Acoustic Panels for HVAC, Pipe, Machine, Window, Wall, Door

Arrived very clearly used, with dirt, black stains and chunks of foam missing.

Returned. It's almost like an x-ray protector but not quite as pliable as they are. Perhaps good for some type of pipe / factory-application, but not for what i needed it to do.

Not only is the foam a good density but the rubber back really helps kill noise.

Too expensive

This stuff is high quality and worked way better than I thought it would. I split it down the middle and used a piece for each rear strut tower and wheel well. I did not glue it to the car I glued quality magnets to the rubber side. It's plenty flexible and this keeps moisture from damaging the car and of course can be pulled right off for inspection. The rear seat holds the rest in place. Amazing how quiet it is to have a conversation with someone in the back seat doing 70 down the highway. Yikes.... if more people understood this it would put the luxury car market in serious jeopardy. Anyway, this was my particular use for it and I am impressed. Also thanks for not shorting the length. I think it was even over by half an inch. Rare these days to get anything that is honest.
