Rated 5 out of 5 by from Money well spent I'm very happy after all the effort i put into sound deadening and insulating my 1968 F100. It is painted black as as I finished in the driveway it was parked in the sun with temps in the 70's. I couldn't hold my hand on the outside of the roof while the underside was just warm.

Rated 5 out of 5 by from Nice product. This insulation is of nice quality and easy to install. I saw several comments concerned about the advertising on the product but that lettering wipes right off with a rag and some lacquer thinner.

Rated 5 out of 5 by from Easy install I sprayed the interior roof with Eastwood Rust Encapsulator and applied the XMat. Easy install, just trim and apply. One box covered about 90% of the roof. 1967 Mercury Comet. The headliner bows cleared the XMat. The sound and heat coming from the roof area is much improved.

What's the difference/benefits between this and the eastwood underhood thermal accoustic mat?

Asked by: ktown
The xmat brand is 1/4 thick and the thermal mat is 3/4 thick which will be thicker to reduce more heat.
