If you do it yourself, buy a quality pressurized blaster and not one of those death traps that Harbor Freight "Made in a Hurry" sells. A USA made vessel costs about $275=325 and will last forever. Get regualr Black Beauty slag and do it in the driveway. Put down some sheet plastic and get to it. I did and its not the mess that everyone claims it is. You can control the media slag very easily. Is it labor and effort? Yes. But its the ability to gain pleasure from knowing you did it yourself that you'll remember for ever.
