I have stripped 3 cars in my time.
The first 2 were paint stripper and the last one bead blast.

For what it costs in stripper, time and lots of mess bead blasting is cheap.
Bead never warped my vans side panels and leaves the metal looking like new. They used garnet on the inside of doors etc where there was no chance of distortion and does leave a slightly rough finish that can be just buzzed off with a sander.

One thing negative I found with bead is I had my m21 and shifter rebuilt no long before the blaster did his bit and my newly greased shifter got a lot of crap in it so I would cover and any greasy bits.

I have looked at soda and this could be perhaps be a better way to go. You can just wash away any residue from out of the car but I had a quote to do 2 guards the other week and he wanted $250 but the bead guy did it for $100.

Bead blasting gets my vote.
