A few years ago I did the inside walls of my Westy with a polyethylene
backed, self adhesive bitumen based roofing product. I don't recall the
trade name (I may have posted it in the archives).

It was less than 1/8" thick but you could lay on as many layers as you
wanted. A roll (like roofing felt) cost me Ca$80.

Didn't make any effort to totally cover body panels.

It worked well for sound absorption.
