Thinking about buying a sandblaster

Been thinking about that,probably will have to upgrade comp,more expense but the time saved will be worth it I think. The amount of work we have to do and the amount of free time to do it in don't quite balance out.At my age 54 I'm trying to work a little faster,smarter,and easier.My goal is 1 car a year starting with the Darts, the Coronet a little more involved. Thanks
