To get to the point this setup is for stripping almost any kind of surface coating off almost any surface. From striping paint/rust off a car body with abrasive media to removing paint from a wood house with corn cob. You can figure on a car body taking from 3-4 hours and the normal cost is $180 - $200 per hour + media. The most money seems to be in the boat stripping market. Every year marinas pull boats out of the water and strip the paint and repaint the antifouling paint. From the other blasters I have spoke with say boats make the most money at about $2000 a pop.
If you have anymore questions let me know. This is a very good setup to start a mobile blasting business. If your in a good area this setup could pay for its self in a month.
