Is it worth the trouble to remove factory sound deadening

[SOUTHBAYeric]

So I got all my old carpeting out and I have a block of dry ice but I am second guessing wether or not taking out the old tar is worth the trouble. If I were to take it out I would put some new modern stuff in. Is the weight savings worth it? I am not too concerned with how loud the car is, and I only drive it once or twice a month so the joy of driving the thing overpowers any quirks or complaints I may have.

Thanks for any advice

I would have to say, leave it in and cover with modern stuff.

Bottom line, what ever you do the area is gonna be covered so who is gonna KNOW or Care?

just my thoughts

if you already have the dry ice and the carpet is out. i'd remove it. you never know what's lurking underneath. replace it with roofing patch available in an 8in wide roll at home depot. it's the cheap alternative to pricey Fatmat and the like.

having dry ice and a blanket to hold the cold in makes short work of removing the tar.

if you are the least bit concerned about rust, remove that tar crap. even if you are drivin' a CA car, rust can form in those dang drain holes. and jerry is right, the job isn't that bad with the dry ice...and it's actually kind of fun, in that sick 02 insanity way.

if there is rust under there as mentioned in the above post.

I see no real advantage to the new stuff over the old stuff.

If you are confident there is no rust there, chill something with the dry ice and move on.

Yeah, man! You aren't one of the devout unless you've remove that stuff. The horror!

[jlandreth]

It will take you some time ,(based on my experience with a heat gun and scraper ),but the stuff does trap moisture. I'm guessing I saved 25 lbs.

chill something with the dry ice and move on.

Yes!

Drop a small chunk in a plastic bottle with a touch of water in it. Cap it off and toss it in your neighbors back yard.

Giggles.

That reply could only come from you, Steve.

I think you should remove it, while sound deadening hasn't improved all that much since your car was built, the ability to reseal the floor plugs and form a waterproof coating on the floor boards is worlds beyond what was used in the 70's, do it once right and you'll sleep better.
