Easy undercoating removal
Trying to finish up the little things on my 64 Belvedere and wanted to remove the undercoating from the inner fenders. The first one I did the old fashioned way with heat gun and scraper, realizing I won't live long enough to finish them all, I decided to look for a better solution.
I covered the inner fender with paper towels and soak it in mineral spirits. The towel conforming to the curves allowed the minreal spirit to soak in. Giving the mineral spirits about an hour, then using a stiff scraper, the undercoating peeled up , took five minutes to complete. If the coating is extremely thick may have to do this in stages.
Beat the out of the heat gun and two hours of hard labor.
 
I've used stiff scrapers on the dry stuff and it does come off "reasonably" well, but you'll feel it in your arms .

Then I finally broke down and tried a needle scaler that was recommended to me by another member . . . boy was I wrong for waiting. Finished the whole area ftom my axle to the back of the csr in about 30-45 minutes - and it has a ton of tight curves to contend with.

Give a needle scaler a try . . . you won't try anything else . . .

Needle scaler for me too
 
Yes, they work really well on irregular surfaces where the putty knife doesn't conform to the contours.
Also works well in removing heavy scale type rust.
 
I have a few different size scrapers and a couple modified wood chisels....... and a bench grinder

Used a torch on mind and it made quick, though smelly, work of it. Definitely want to have GOOD ventilation!
 
So for you that have used a scaler,,,does the needle scaler work as fast on undercoating as it did on that paint in the video? Does the needle scaler deform the metal in any way?, looks like it would beat the crap out of sheet metal. Thanks

You can also use aircraft remover put her on with a paintbrush let it sit for a few minutes and then you can either scrape it off or hose it off with a pressure washer it all comes up
 
A long time ago I brushed on some used ATF.
I don't remember how long I waited probably 24 hrs.
It worked pretty well on softening the undercoat, and it was cheap!

I have done the heat gun & scraping technique and also the needle scaler. I haven't tried it but after I did mine I heard of using some sort of steamer & it melts the under coating right off.
