Having a blast....soda, that is, soda blasting recommendations Options

[porbmw]

So
I would like to strip body of car down...
Have taken a prior car to the shop, to use walnut shells
Would like to do this on my own
I DO NOT have a large compressor...most I have is the portable 110volt that I can carry around to do home construction repairs etc

a)Will "that size(sorry, don't know how many gallons off hand, bigger than a breadbox, I'd guess 5 gallons?) do the job..I appreciate that the smaller the compressor, the longer the job takes

b)where would I buy the soda attachments...and what kind

Duh...pretty vague/uneducated/uninformed question...
Thx
Paul

best idea - just hire it done after you strip out all the soft parts & glass & have a body shell left

circa 1977 - i did my car the hard way with chemical stripping followed by gentler mechancal sanding - anyway you do it is a mess

- catalyzed aircraft stripper works best if you can still get it - which maybe you can still buy in Canada (tho it eats fiberglass & bondo etc as well) - even then it is a multi-step process cuz it does not uniformly "eat" all layers at same time

mechanical methods suggested above are time sinks especially if you have multi-layers of repaint to deal with & is very hard to do well on curves & depressions meaning you'll have a lot of "filling" work to do afterward)

- even then, good air sanders & DA's require a hefty compressor & our old school 7" electric grinder-sanders like Souix & B&D with coarse grit discs will cut into the surface

i chem-stripped a Corvair Corsa back in the late '60s, but in those days GM oem paint was lacquer & you could use DuPont lacquer removing solvent that dissolved the surface paint & left the under-coat oem primer intact - (a relative "piece-of-cake" resto project it was)

iirc the lacquer solvent would also work on repaint enamel which is softer than oem baked, but have not seen it available for a long time
