i have been looking and thinking about a good and cheap way to cut down on the sound in the cab of my 27 chevy pickup.
i looked at dynamat and the asphalt roofing sheets some folks have used.
i have four demands of whatever i use
1 super cheap
2 it cant soften in the brutal heat of the southwestern u.s.
3 it cant stink
4 it needs to actually work
it is my understanding that the sound deadening is achieved by cutting down on the harmonic vibrations of the sheet steel (among other things)
then i had a brainstorm.
last year i repaired a mobile home roof with a rubber based patching material that dries into a fairly hard but flexible rubber (think tennis shoe sole)that doesnt melt in the sun.
it is applied with a trowel.
so i am going to use this stuff.
i paid $12 a gallon.
trowel some onto the inner roof and doors as well as everywhere else before i put a heat barrier layer .
then put some kind of paneling in.
anyway i just thought i would share my idea.
any thoughts?

p.s.
heres the stuff.
