I first cleaned everything with alcohol wiped all down. hit all spots with some black gloss paint..ran three layers of 80 mill deadner and used heat gun to roll it all on..then layeed 5/8" thick carpet padding then carpet..then built that sub floor and did all those side windows and rear window.Still need do my roof and seal everything off and try finish up so I can get started back on finishing up the wall.Talking about quiet in there?? I can barely hear any road noise if any at all.I can hear air coming from the front window when driving..Lookslike Ill need to reseal this windshield again(#4)
