How can I keep the
Street noise down over the axle and engine?
Torch down Rubber Roofing is great for
sound deadening ,
However, it does not have to be torched to be efective ..
You can use it with 2-3 layers of 1/2" sheet rock or very thin sheet lead
and sheetrock to form about
the best sound deadening properties money can buy
within a given budget
