My sound deadining projeck Options

[jsayre914]

Well,

I am waiting for my exhaust to come back from the ceramic coater, so why not start the next project (IMG:style_emoticons/default/biggrin.gif)

I just recieved my shipment of second skin. I bought the damplifier, overkill and luxury liner. I am not sure if i will use it all but I want to see what works better where. I will post some pics once i get underway. I already have an aftermarket engine bay pad from evil bay. it works pretty good. this stuff i just got will go on the interior only. I also plan to reinstall the rear window with some new butyl tape when i begin. (just say NO to water)

i wonder how many projects i can start at one time (IMG:style_emoticons/default/idea.gif)

here is the link to the stuff i bought

I've been thinking about using a different approach.

I just don't like the idea of scraping off all that old tar and fixing the rust to then seal everything off afterward so water can get back in and start rusting my car again.


So, my idea is to paint the floors etc. after rust removal and then add the sound padding material to the backside of the carpet.

I think this would still work pretty well and makes for easy removal to inspect the floors every once in a while.

A few years ago I wanted to build a quiet Beetle, so I pulled up sections of the floor covering on some "modern" cars that were available to me: Mercedes sedan -- inside, I found paint, wool felt and wool carpet. Underneath the pans was an applied elastomeric coating. Acura Integra -- Paint, rubber, foam, carpet. No undercoat. Chevy -- Paint, foam, rubber. None of these cars used much if any cement under the interior finishes except at a few spots.

My conclusion was to apply an elastomeric coating underneath, but keep it "loose" inside. I went with a customized rubber liner over the fresh pans, felt and German carpet. I did insulate the engine bay with a heavy applied tar board. Can't remember the vendor. It was quiet.

It's apples and oranges, but I think strategies dealing with resonance and wind noises are more effective than blanket "insulation" underneath the interior finish. How that applies to 914 I haven't quite figured out yet. I also think that blanket insulation will work as well to eliminate noise, but the stick-on applications are less satisfying if you consider the potential problems "down the road."

This is a neat thread with a lot of information and where the opinions expressed are based on expertise instead of conjecture. Thanks for that.
