I have been using Les Schwab for years. Just took in 8 this summer and the price was $26.50 each. That was for blasting, acid washing and powder coating. Guy said all the stores can do it but most don't know they offer that service. I used the one in South Seattle as they do lots of semi truck wheels. They sent them to their facility in Oregon and it took about a week. A little secret I tell people when they complain about paying $50 just to have one blasted. Until the one guy started scamming people with the "just spent $500 having these wheels blasted and powder coated. Will sell for $400."
