Re: sand blasting questions
I warn against just using sand... it will embed contaminants, and leaves a rough (sharp) finish.
Go with clean glass beads. I'm not sure of the sieve size, but they are small (like grains of sugar) blasted at ~60psi. Just a quick back and forth dusting is all you need. If it comes out blotchy, or un-even part to part, you probably blasted it too long.
