A friend of mine has just started a dry ice blasting business for cars. His target customer seems to be high-end collectors, the ones with many high-buck vintage cars who will pay $1,000-$2,000 to have the undercarriage blasted with amazing results. As he's just started, I don't know if he'll succeed, and I haven't asked his start-up cost.

Seems to me you'll blast a car once, and never see it again, because these cars are basically not driven enough to be repeat customers. So you'd better be in an area with a whole lot of this sort of collector car, and have the inclination and social skills to get in tight with all the formal and informal collector car groups. Your facility should be able to handle having very high-value cars driven or shipped to you and securely stored until their wealthy owner has time to pick it up.

Not different from other shops that specialize in high-buck collector cars - except that they will make five figures in revenue per car, and you're making low four. It would be good to offer add-on services - detailing seems the obvious one.
