Where can I find something in bulk that isn't too expensive. I'm trying to quiet down my interior and seal the bottom of the car better. What type of undercoating can you reccomend? I also plan to you some liquid sound deadener inside the car, along with brown bread and lcomp.

 

walmart sells undercoating that's pretty cheap. You only need 4-5 cans to do everything.

 

where do you get liquid sound deadener? Can you paint over it?

 

Go to any local multi-line jobber (e.g. Auto Color) and tell them what you just told us. Likely you'll be shown some 3M or PPG products. They are better than OEM quality, and will do the best job. They are, however, not cheap. The walmart stuff I am not familiar with but it will probably work ok. Just don't put too much near the exhaust area and certainly make sure your heat shields are in place. Some of the aftermarket stuff is flammable even after it dries, and our cars get MUCH hotter than a normal vehicle down there. For spraying the inside panels parts express (http://www.partsexpress.com) sells some of that spray dynomat type stuff which supposedly works nicely too. Realize that sound deadening material adds some significant weight to the vehicle so if you are wanting to drop time on a 1/4 mile at the same time the two goals are mutually exclusive. But I don't think that's what you want to do.

 

Actuallty I completely stripped my interior and removed the sound deadening tar. I was just curious. I'm going to be painting the interior in about two weeks. And I plan on covering the trans tunnel with a combination of the stuff from fc3s.org's store. (It gets WAY too hot)
