Meadia blasting is fine but as recent as last week I was told by then hydro testing facility I use that they wont test any aluminum cylinder that have been sandblasted. According to them it has to be failed on visual because there is no accurate way to determine how much aluminum was removed by sandblasting.
Should be no problem to find someone who uses glass or walnut hulls.
Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB
