Gary, Marty:
    Soda blasting is the perfect media for this type of  work. In fact soda 
is so good for Autobody panels that you do not have to mask  off glass or 
chrome. It will not be harsh enough to do any damage to your body  panels. It 
is 
pretty soft, so you cannot reclaim the spent soda to reuse, once  it hits a 
panel it is smashed & not reusable. It is very environmentally  friendly. Also 
when you use soda, you do not have to degrease first, the  soda will clean off 
the grease & oil at the same time, unlike other medias  where you need to clean 
the item first.
    Because it is so soft, it will only  remove the finish, it will NOT 
remove rust. If you have rust you will need  to remove that with a harsher 
media 
(black beauty or glass bead). But be  careful when you use the harsher media, 
as 
this will hurt the panels if you do  not reduce the psi. I have a TR6 bonnet 
that was ruined by a shop that used  high psi. & harsh media.
    Soda is water soluble & can be rinsed off  your panels with water. The 
soda residue also prevents rusting while you wait to  prime & paint.  
    As for consumption ... most "soda blaster" systems  use about 1lb. per 
minute. So a little more than a 50lb. bag per hour. 
    Search the web, there are many companies that rent  out soda blasting 
trailers with built in air compressors by the day.
    As FT, pointed out. Never EVER use sand, unless you  want the big "C" 
cancer!
    Good Luck!

Marty, when media blasting a body or panels care has to be taken or  the heat 
of the stripping will warp the panels and depending on the media it  can pit 
the surface too.  Baking Soda is pretty safe, as are a couple  of others as 
long 
as you take it slow and keep the pressure down.  But  for heavens sake DON'T 
use sand on anything you want to be straight or have  a nice finish on.  The 
biggest problem, in my opinion, is people get in  too big a hurry and use too 
coarse a media with too high air pressure.   The combination of which will 
leave you 
doing more work that stripping the  paint with a brush on chemical & scraper.
