John,I used the Peel and Seal stuff from Lowe's and/or HoDepot when my real sound deadening material from B-Quiet ran out.  The roof stuff costs about half per square foot what the real stuff does and appears to be the same thing, tarry layer with foil backing. It was in the van at the time we met you on our Alabama trip. I used three rolls of the real stuff in the back of the van when I removed the Westy interior to inspect for rust and to add some kind of soundproofing. I used the roof stuff in the front doors only, because I did not want to reorder from Canada before leaving on a trip.  I can tell no difference between the two products.  I did experience some of the roof stuff peeling off inside the driver's door one summer, but I reapplied it and foil-taped the seams and cleaned up and have had no problem since.  I will eventually do above the front headliner and under the carpet with the Peel and Seal. The seam taping is advised since the tarry stuff can reach places you'd rather not have it. The results can be impressive.  I suspect the Westy configuration is less improved because of what you cannot cover compared to the tintop's interior but rapping any backed panel gives a satisfying thump instead of the stock sound. It's not an easy task but it's a pretty simple one that gives results.  Stephen

Didn't think of that. What exactly are you using to cover that part? Any use in using the regular mat and sticking it to the back of the door panel?
