I restore old cars and there is no one close that Soda Blast's. So I was going to purchase my own equipment. My question is: Can you run soda through a sand blaster and have it work. I was told you could but find nothing of the mention of it. Some cars need to be soda blasted and some you can sand blast. I would like to get ONE machine that does both with good results. Any help??? And any recommendations on equipment. With taking cost into consideration. .I restore for myself maybe a car a year.Thanks
