I'm starting a mobile media blasting business, and would like some advice. I'm currently in the process of purchasing a MMJL sandstorm Mobile trailer setup. The pot is a multi media largest pot they sell. I have read a lot of conflicting information about soda blasting cars. I plan on practicing a lot on junk cars what ever I can get my hands on. I have a job lined up already to strip a red brick house, but I have to say I'm very concerned about getting more jobs. I have a loan payment due every month and plan to market the best I can. Any suggestions would be helpful.
