Re: SODA BLASTING (hungpham214)
Here was a response of mine to a person who inquired about sand blasting their interior a while back. It may have some useful information for you.

What you need to do first is get all the tar out with dry ice, otherwise the blasting will take FOREVER. I think I ended up using about 40lbs of pelletized dry ice (two different 20lb sessions due to the 100* heat). This cost me about $20.
There are several types of sand you can use. The best would be a sand designed specifically for blasting. This is what I used. A place called Steve's Wholesale Tools sold it to be. It's filtered, washed, and kiln dried. An 80lb bag of this was $4.99. I think I used about half a ton of sand on the interior and engine bay.
PLAYGROUND sand will NOT work. The grains are too big and it's full of trash that you don't want in your sand blaster. Not to mention the fact that it's loaded with water to drive the weight up, bad for blasting.
You could buy actual blasting media (i.e. glass beads), but it's not necessary for the interior, plus it's very expensive. You can also use baking soda because it's less harsh, but you're likely not looking for a super smooth paint finish on your interior. I was going to use baking soda on mine, but 50lbs cost me $20, so it's quite expensive as well.
You will NEED the proper gear to do this. A face shield, preferably a "hood" is best. They sell these with media blasting equipment. This is not optional, unless you plan on loosing skin and/or damaging your eyes. Also where gloves, long sleeves, and pants. You can try it without, but it's not fun.
Prepare to have sand in places it shouldn't be. That applies for the car and you.

I'm sure the baking soda can be had for a better price. The stuff I bought was from Sam's and at the rate I was going, it would cost a fortune to do an entire car.
One of the benefits of using the soda is that it leaves a smoother service. The soda also dries out the metal. Many blasters claim that you can blast and entire car with soda, down to bare metal, and not touch it for months and it won't rust (provided it doesn't come directly in contact with water).

Re: SODA BLASTING (-NA-aLL-thE-wAy-)
this what i got from the site
Soda Blasting is a process where virtually any surface may be cleaned or depainted. Blasting with soda is similar to sand blasting except that higher caliber equipment is required and that sodium bicarbonate (baking soda) is used as the blast media. Soda does not damage surfaces being stripped or cleaned; does not cause abrasions or warping.
Pre-washing or masking of the surface is not necessary. The dust, unlike that of plastic media, is not an explosive hazard, nor is sodium bicarbonate toxic. It is biodegradable and can be washed off with plain water.
WHY USE SODA BLASTING?
Some of the advantages:
Ø No toxic fumes or chemical solvents required
Ø The media is relatively soft at 2.5 mohs hardness
Ø No sparking, non-flammable, non-hazardous, water soluble
Ø Gentle yet effective cleaning with a minimum of disturbance to the substrate
Ø Will not etch glass
Ø Will not damage bearings or seals (product is friable – breaks on contact)
Ø Food grade approved
Ø Generally more aggressive and less costly than dry ice
their rate is around $1000 to blast all the paint, inside, outside and under
