SOUND PROOFING INTRO
************************************************************************************************************************
Well for anyone who has ever owned a 3rd generation Firebird or Camaro, you know how they rattle. There is a ton of road noise and you have to blast the stereo to drown it out. Or heaven forbid you want to have a conversation w/ someone in the car, you have to yell to hear over the cars rattles, road & wind noise.
So I decided to sound proof, not just for the rattle & noise elimination, but for the increased stereo performance. W/o rattle, the stereo has less noise to overcome & you actually hear the whole sound spectrum. Not to mention the fact that is makes the whole car act like a sub box while you are inside. With less bass and music escaping to the outside, it intensifies the experience!
So the next few pages will detail what I did to quite these annoying creaks, rattles, wind, and road noise.

My first step was some research. I talked to a friend in a local stereo shop and got some good info. He said the key to soundproofing is to make the metal and interior pieces more dense so they are less likely to vibrate. By eliminating the vibration the panels will be less likely to transfer noises. This will keep the outside noise out and the stereo sound in!
1) Dynamat is awesome, but expensive and heavy!
2) Spray on Dynamat (blue stuff)...don't get it wet it breaks down and runs.
3) His trick for interior panels...glue the sub box carpet to the back of them and they will further reduce the vibration transference.

So with this info I set out to soundproof the car! As luck would have it, I was looking for some type of waterproof spray on sound proofing. Well at AutoZone I found some Rubberized undercoating and some of this!
Well I tried both. One on one side and one on the other. After a trial run...the "Sound Eliminator" was by far superior!
Its consistency is like tar. It goes on thick, unlike spray paint. It dries to some extent, but is always rubbery. It will become sticky at times in intense sunlight. Now gas and degreaser will make it liquidy again! Water, no problem! To solve the sticky problem, I went back and used satin black paint over the final surface to seal it.

No melting in the heat with my coating, but gas will make it melt as will other car chemicals! I would say heat softens the stuff, but all mine is out of direct sunlight and is undercarpet padding, or under paneling... so it causes no problems! In the dead of summer sitting on hot asphalt I have never noticed the underside coating melting, though I sealed it by painting it.
