That would be undercoating. Scrape as much as you can with a putty knife and then heat it with a heat gun and scrape some more.

If your car is a rolling shell you may want to get some dry ice.  Google dry ice and undercoating.  I've done it many times and it's super easy and clean.

brush lacquer thinner on it heavy, let it sit for a couple minutes and use a paint scraper the husky multi tool one with the paint roller wringer and and pointed other edge work the best or a narrow 1- 1.5inch scraper just sharpen in a lil on one side, they even cut spot welds if you use a hammer, or use an angle grinder and wire wheel, but you will be sound deadened if you do lol

I have the gas tank out so I decided to remove undercoating on my 71 at least from the wheel wells back. After trying a few things I found that that a mini needle scaler 20.00  (if you have a compressor) worked well on heavy spots on back frame rails. Once I hit with the scaler for a few moments I could scrape off pretty easy, a very tedious process no matter what.
I am going to use a couple coats of zerorust (no top coat required) on it and then apply undercoat to rear wheel wells (there was not much left in this area)

Tal Strip 2 aircraft stripper gets it too. It is expensive, but eats right through it. If you have the option, avoid the spray can and get the raw can you brush on. You get a lot more for your money that way.
