My new hidden interior mod Hidden under my carpet! I sprayed some Al's Sound Deadener in the car. I was hoping to quiet down my interior a little bit so my son doesn't go deaf like I am. 
Car was 83db at idle and a shade over 100db at WOT. We'll see what it is when I get it all back together.
I had a broken drivers seat and was swapping in a T56 anyway, so I figured I'd just yank the rest and spray this stuff in.
Unfortunately my window tint got torn in the process, but that just gives me an excuse to go darker.

I'd imagine it would a bit, that's one of the reasons I went with the lighter grey. Not sure though. I shoulda busted out the IR thermometer for a before and after.

It wasn't hard at all. The main part was taking out the interior. Taping and masking was a little time consuming, but it was really easy. I got a bit of overspray, but it cleaned right off with some denatured alcohol.
I'll try and do a write-up tomorrow.

4th Fbodies have terrible insulation. More and more people are doing insulation mods.
I just ordered 125 sq. feet of Raamat. I was going to go with the spray-on stuff but after revewing Raamat and some closed cell foam, I figured thats the way to go.

I sprayed it. I have some Second Skin matting in my shop I might use too, but I wanted to see how well this worked as is.
I have owned so many cars that had rusted floorboards from wet carpet that I wasn't about to put ANY matting down until I sprayed a rust-proofing liner in it. Especially an f-body that will eventually leak, no matter how well you take care of it!
One thing, when you reinstall the carpet, make sure you have help. I did it alone last night and the roughness of the deadener made it really tough to slide in the carpet.

I too and looking to do this, you did an awesome job. When you get it back together give us a reading at idle and WOT so we can see the difference in dB. I think I've talked myself into the spray on stuff, then maybe matting in a few trouble spots. Its difficult to pick out a good brand, everyone has different results and every seller says theirs is the best. I'm waiting to see how yours turned out, it sure looks good.
looks cool though, i can't wait to see the sound results
