If you only plan on blasting one car, once, it may be cheaper to have it done professionally, than to purchase all of the necessary equipment.

==Sandblasting sheet metal==
+
===Soda blasting===
Sandblasting sheet metal is controversial, and often ill-advised.
+
Soda blasting is the use of sodium bicarbonate ("baking soda") as a blast medium. For more information, see: [[Soda blasting]].
 +
Never soda blast cars still together as the media gets into electrical sockets and connections and will cause chemical reactions that can and will cause a myriad of problems.
  
*Prolonged sand blasting of thin sheet metal causes frictional heat (''frictional heat, or peening?'') that may cause the metal to ding, warp, or pit. Be aware of this if you especially are going to be doing a long, flat, unsupported body panel. The best way to avoid this on long spans is to spread out the blast from the gun so that not one area receives the brunt of the abrasive blast for a long period of time. It also gives it time to cool.

*Most media recycles very nicely, with the larger particles breaking down into smaller, sharper ones. Eventually, it will be broken down so far that it cannot diffuse into smaller particles, and the media will have to be replaced.

 +
==Preparing surface after blasting==
 +
Be certain to follow the primer/paint/filler manufacturer's instructions for preparing the surface after blasting, for proper adhesion.
  
 
==Safety==
 
==Safety==
 +
There is no "safe" blasting medium. Use the proper safety procedures.
  
The BARE MINIMUM when doing open-air blasting is-  
+
"Abrasive blasting with sands containing crystalline silica can cause serious or fatal respiratory disease." -- [http://www.cdc.gov/niosh/92-102.html CDC: Preventing Silicosis and Deaths from Sandblasting].
(for when you first start off)
+
  
 +
===Protection for open-air blasting===
 +
====Bare minimum====
 
*Long pants and sleeves

*Leather gloves (media doesn't feel the greatest on your hands when coming out at 100+ PSI)
 +
*Respirator (NOT a cheap paper one, the cartridge-type is the one you want). Read the MSDS sheet for the blasting medium that you're using, and use the recommended respirator and/or personal protective equipment.
