Tim,
The stuff I've used is Paasche AEX. It's been a while since I
bought any and at the time it was all that was available IIRC. Now
they call AEX fast cutting and they also have AE (medium cutting) and SSO
(slow cutting).
I poked around on their site and found the MSDS for these products.
AEX is aluminum oxide--no grit size given. AE is pumice, and SSO
is food starch. Possibly one of these gentler compounds would be safe
on painted items but I'd be cautious.

What is the grit size for the Paasche aluminum oxide ? The label
has no
size information. I've used the Badger grit and it seems more
aggressive
than what I use in my booth which is 220 grit. I've tried to
use baking
soda but it seemed much too soft, made a huge mess (in the
garage), and
definitely is moisture absorbent.

I've used an older Paasche LA-3
abrasive gun for some time. The LAC-3 is the current version and
has a carbide tip for better wear resistance. I use it with
Paasche compound for prepping brass for paint. I used to use it
only outdoors but now have a cabinet. I found a cheap Harbor
Freight blasting cabinet on closeout. I threw out the HF gun and
use the LA-3 in the cabinet. I'm quite happy with it and Paasche
products in general.
I've never used the LA-3 on plastic or any
painted surfaces so can't say how it would work. But I suspect it
might be too aggressive and that the air eraser with a milder compound
might be a better bet.

it today to try to sort it out but I also went online today to see
what is out there. TCP Global shows some Chinese Guns that I will look
more closely at but I wanted to ask folks here if the have experience
with either of these Passche Models:
