OEM undercoating removal

[hemi68charger]

Hello All,

I probably already know the answer, but I'm looking for other experiences in removing the undercoating that comes with the sound deadening option on the floor plans on our mopars. I'm getting ready to initiate the paint and body for my recently purchased Charger 500..

There's the old tried and true propane torch and putty knife...

also found this..

Did the old torch and putty on my fully undercoated 72, took a few hours. Some pieces came off in chunks.

That looks great...

And when it's all done you will end with a pile about this much. About a 5 gallon bucket full of under coat. Took me about 12 hours total time. I'll tell you one scraper you won't find in the tool box. I used one of the wife's table spoons to scrape in the rear wheel wells. It seemed to have the right contour. When you start you will see what I mean. A wire brush helped also along with some 3-m scratch pads for the final wipe.

I used a heat gun and putty knife. Seem to work just as well as a torch. I think I could control the heat better with the heat gun. You have to love how the undercoating protected the metal. Most of mine was clean metal under the undercoating, except where the undercoating was lifting.

Here is an option of using a needle scaler

Ive done a couple of them this way after trying a hot water pressure washer ( didn't work worth a hoot ) Both I id the car was on a rotisserie so I wasn't laying on my back on a cold floor makes a HUGE difference btw  .

A cheap propane torch, one of them with a button start makes life a little easier and a 1.5' metal putty knife  works best ( I like the spoon  idea for tight areas )

FYI, it doesn't take much heat to lift the undercoating so there's virtually no issues to worry about warping panels.
