Im thinking of sandblasting my body when i get ready to paint it. What size sand should I use and once i have most of the car stripped wont i have pits everywhere? I have a 45lb cheap sandblaster that I might as well use for something.

Theres a guy that lives about 50miles away that does soda blasting but im pretty sure that would be expensive

This is one of those "ask me how I know" replies but you don't really want to blast sheet metal. I warped every panel on my car, roof included. I used silica sand(the white stuff) and had no pits but short of holding the nozzle 3-4 feet away and finishing sometime in say the next decade, you just don't want to do this.
I'm sure there will be people who disagree with me but that was my experience.

Anyone done soda blasting?

NO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
if anything go buy a pressure pot and find a place near you to buy plastic media it is crushed up buttons this doesn't generate heat and wont warp the metal. now the bad news it doesn't remove rust but it will take allot of time and does take all the paint off and wont hurt anything else. it also wont hurt plastic or fiberglass. if it were me I would shell out the $700.00 to $900.00 and have a professional shop do it 3 days and you have it back ready to go.

what I have done with blasting is if it's sheet metal, it better be a spot blast, or else use a grinder

A 7" - 9" grinder with a twisted wire cup on it will strip paint faster than I've seen any blaster clean anything. I stripped a full rear quarter panel to raw bare steel in 15 minutes and the $15 wire wheel could have lasted to do the whole car.
It works pretty damn good on surface rust too. Then you can lightly sand the thing at low speed with a fine disc.

I had my car soda blasted, it come out great, the only draw back was it didn't remove any rust and there was soda everwhere. But you'll get stuff everywhere no matter what you use. The soda can be washed away without much trouble. Jim

The guy by me "Doc Stripper" uses quartz oxide. Excellent, with no panel warpage. How the guy is still breathing after 25 years of doin this is beyond me, though.

Sand blasting sheet metal is best left to someone who knows what they are doing. If not your car will look like a moonscape. There are places that do plastic media blasting that I have used on corvette’s that works really well. There is a place above Allentown Pa. that dips the whole car and it removes all traces of paint, bondo and rust but the problem with that is you have to reseal the whole car. There is no easy way to do it.

at my job we have all the bodies plastic media blasted,it works out great (except on Corvettes-long story)and does remove most of the rust.the guy that does it for us said he'd do my Camaro for about $250.00.now granted this is probably aspecial price,but even if it is half price $500.00 is still not bad.however when you get up to around $750,I think Alkali dips are a better deal for the price(about a $1000.00)

There is some place in the San Francisco bay area (I can't remember the name) that uses dry ice to blast cars. No clean up when you done the dry ice just goes away.
