Tar-like undercoating on 63 Valiant...any way to remove it?

I posted this April 30, 2020
Removing 55 year old undercoat from your restoration is, to say the least, something that can be time consuming and just "sucks canal water." I've watched videos and read articles about it. I've used an air scraper, (fair) heat (fair) paint stripper (nope) and even oven cleaner to try and expedite its removal. I would like to share something I discovered by doing something "just for the hell of it." (of course I may not have discovered something that has already been discussed on the forum, if so, I haven't seen it.) I "generously" sprayed (wet) my fender wells with "Goo Gone Automotive Spray Gel," just to see what would happen. It was late in the evening so I decided to let it stay on over night. The next day I was blown away about how easy it was to remove the under coating. I was so impressed I had to make this little video to share. (Let me add...I did a final clean up with my pressure washer, mainly to get rid of the residue)
