Sounds like 3 of us had the same thoughts lol! But back on track, the last time I chemically stripped a car, I used IIRC a product called Tal Strip. It is(was) some nasty stuff - better have gloves, long sleeve shirt and face protection - but took the pain off pretty much down to primer and in a lot of cases down to bare metal. Being so nasty I seriously doubt it’s even available to the public nowadays.
