If it's hard as a rock the blaster guy didn't try.. But that said a needle scaler is effective.. As is a serious steam cleaner..

I usually do the same, propane torch with a scraper, then blast any residue that's left. I'm sure there are easier ways, but for cost, a propane bottle is cheap... takes some time, but it's not hard work.

Steam cleaner hands down. Turn a hot burning week long messy job into a 3-4 hour aftenoon job with a 10 minute cleanup. EASY choice.
But now he can't use water because his car is bare metal now and it will rust bad if it get's wet.
Always steam clean with a pressure washer before media blasting.
I do the whole car top and bottem long before media blasting to ensure a grease and oil free car before blasting and then it's ready for primer within minutes after blasting.
Even though I don't agree with silver70, it is too much senseless work for me to scrape it with a torch which damages the bottem of the car with scrape marks.
I think this might be the OP only choice now unless he primes all the bare metal and starts over with washer and then blast again which is really bad for his sheet metal because media blasting stresses the metal, imo.

Did my 72 on my back in my garage with a scraper and torch from Home Depot, it's probably the only car I will ever be restoring so I have the patience to do this method and cheaper for me. A lot came off in decent size pieces so that was nice. For me cleanup was no big deal, didn't mind doing it.
On your back it would be impossible to use a steam cleaner, you would get burnt. Looks good .Check this out, couple hours and I had this. Not a speck of undercoating left anywhere and leaving all paint in place.
Maybe the OP should leave the undercoaing there and add to it??

I used a little torch and a scraper for my RR. What a pain.

You can rent a steam cleaner at most any rental yard for under $100.00 a day. I suggest the largest/most powerful model they have. What I like about the steam is it does ZERO damage to the original metal. It will also leave all the original paint,primer,inspection markings, etc. Unless you actually try to remove them.
I wouldn't even know where to rent one here... plus that's $100 I can spend on something else Honestly my favorite part of these cars is the building, so I don't mind if some things take longer. Once they're done, I usually get bored with them.

For the guys the do steam cleaning, what does the equipment look like and where do you rent it? How is it used? Like a pressure washer or? Looks like a good idea for cleaning and removing undercoating. Thanks Mike

We have 2 steam cleaners none of which will remove undercoating! If it is flaky it will remove the flaks , none of the hard stuck on product but if your having luck with it use it!
Mine is a 4 gal per minute machine at just 2000psi at 212+ degrees, it'll blow mortar joints out of brick buildings, it'll remove under coating.
Thing is most people don't have access to or have never used a higher volume machine. Did you see my pictures in all the other threads? They tell the story.
And someone mentioned about trying to do it without a rotissierie, which I don't think it could be done very easy if at all, because the wand is pretty long and you would not be able to shoot the car at every possible angle to get it all the way clean.
This machine has a steam valve that can be opened and allows some of the water to recirculate and get to the steam level and shoots at a reduced pressure. I do the whole car with it set on high and then use the steam to loosen/soften the hard stuff and then turn it back to high and it'll blow away all of it.
I have done several cars and it took about 4 hours to do the bottom and be completely done and have a spotless bottom.
