How to Remove sound deadner

[zarl911]

What is the best way to remove sound deadner, in a early car?

These were generally my weapons of choice through out my stripping process.

The oscillating multi-tool works best on hardened material. If it is still flexible the abrasive wheel or flapper discs work better.




Don't forget about ventilation/filtration mask! Hope that helps.

I chose a cup shape wire brush mounted into a standard angle grinder. I have heard good reports about the oscillating multi tool with the non serrated flat blade.



Gloves, earmuffs and a full face mask and safety glasses/goggles are preferable. I initially had just safety goggles on and had to pull a piece of wire out of my forehead when I stopped for a break, I did not even feel it go in. After that I put on a shield like a welding mask.

I also tried an air chisel, bad idea, OK on the flat but it made a hole as soon as it got near a moulded section of floor pan.

Heat gun works just fine, then a clean up with thinners.

A bucket of results of my sound deadener removal off my 79. Tar like substance. Easily scrapes off with some heat.

I first tried a scraper, but it chewed my hands way too much. I then bought a cheap wood chisel (about 1/2 inch wide), and used that as a scraper. It has a far better handle than your average scraper, and as it is sharp it is really useful at stripping off the undercoating. The stuff pealed away in no time.

I followed that with a cup brush on an angle grinder. Once all was done I took to the panels with a cloth liberally soaked in mineral turpentine, and finally finished the job off with an ammonia based cleaner. Did this all before I even knew of Pelican and was really surprised to see so many complain about what a tough job it is.

Oh yes - I tried to see if a heat gun would make things easier but that was just messy. Parking the car in the sun for a few minutes was far more useful.

Heat gun and scraper, then solvents. No need to damage whatever finish remains on the floor pan.

I used the straight pick from my Snap On pick set. Was able to place it at a low angle under the tar and with slight pressure the chunks would break off in large 2 and 3 square in pieces. Did both sides in about 45 minutes.

I was able to use a sharp chisel and a hammer to break up the stuff. It was a little easier in my case because some idiot (ok... an idiot prior to me) tried to jack the car from the floor pan. When the floor pan dented upwards it cracked the stuff so at least I had a good starting point

The stuff some people do, right?

You know there is a bright side to being foolish. Sometimes I just think about all the great experiences I would've missed out on if I had known better. The crap in the bottom of the floorboard. Replacing the headliner. Being able to start the car without a screwdriver. Fixing the shifting problems. Getting the CIS sorted out. Hunting down electrical gremlins. Taking care of some rust before it became a real problem. Yea... good times.

Mine took a little longer but definitely did not need mechanized assistance. Did they use different materials over the years?

Is that just the rear firewall or the entire floor pan?

also, did you weigh it?

[javadog]

I weighed mine...

From a coupe built in 1977:

L&R inner door pads 987.5 grams
Right front bulkhead (2 pieces) 469 grams
Right floor 2859 grams
Left floor and bulkhead 2796 grams

You might add a handful of grams for the tiny amount not removed by mechanical means that was removed by solvent.

No questions about the scale accuracy, please. It's fine.

I'm not aware of anything on the rear firewall.

For those keeping score, I think the stuff put down in the era of the 3.2 Carreras was a little different.

so what should I use to take out the sound deadner in my 66?

I believe you can use dry ice on the floor pan

[javadog]

It's easier to use a heat gun and a scraper.
