Sound deadening on the floor. Anyone have good tips for removing the tar like sound deadening? This is an Arizona car, which means the tar has baked on for 40 years.

Hey there. I feel your pain. I also had an AZ car.

Search is your friend. Lots of threads on this. Here's one...

Basically, a combination of heat, a multi-function tool, and a putty knife are the weapons of choice.

Thanks for the link. I tried to search for threads on the site before posting. I'm not sure what I'm doing wrong as I don't ever get any returns from the search.

Heat gun plus a scraper worked wonders

I still have the sound deadening tar in my car.

If the metal underneath is not rusted why take it out?

It's pretty cool
Don't try to remove until you have seen this.

Mark
That is ingenuous!
After all the hours with heat gun I am amazed. Was that just water added to dry ice?
Thanks

OK guys, I just got done trying this. The video was a bit short on details, I used 9 lbs of dry ice, and 1 quart of 70% isopropyl alcohol. I crushed up the ice using the head of a hammer. made the slush, just like in the video.

Put it in one of the 4 sections of the floor panel. after letting it sit for 5 minutes, went in with a putty knife. Pretty soon after that, started using a hammer on the putty knife. long story short, it was pretty much the same thing using the dry ice technique, as just brute forcing the other side with just a putty knife and a hammer.

Given it cost me 20 bucks for materials, and it didn't save any time or effort - for me and my 72 - it was a bust. The issue seems to be that the material is just pretty much tar at this point, and it really adheres to the metal. anywhere there was a crack in the liner, you could count on finding rust underneath that spot.

Back to the heatgun. What a disappointment!

snap on makes a great tool for removing all seam sealer and I am certain it would remove that stuff as well!!

You are probably right, but I had the floor board covered with 2 inches of slush, and it sat there for over 1/2 an hour, as I tried to scrape off portions.

Not sure what I did wrong. I was just reporting that it did not work for me!
