If you go to someone who's business is blasting they have alternatives to sand that isn't as harsh. I use aluminum oxide in my blaster and it works great. The little bit of pitting you do get will be filled by a good quality scratch filling primer. A couple of other tips. On older cast iron boxes I use a strong mixture of Red Devil lye and hot water to years abd layers of paint off. In some cases I haven't had to sandblast using this method. A stiff scrub brush and cold water and it's ready to prime. I found out the hard way though that this DOES NOT work on Herculite and newer aluminum boxes. It eats them up. There are no threads left in the screw holes either.
