Adhesive surface prep question

I decided to get a blast cabinet after reading the glue wars and how sand blasting the tangs was found to be the best surface prep. But I am at a loss as to what media to use to blast with. I am using "medium" glass beads and the finish seems too fine to promote good adhesion.

What's the recommended media to blast with for gluing?
 
the most aggressive media you have. 80AO or 60AO will work good. Glass beads are a little too smooth.

Thanks. That's what I figured when I saw the finish the medium beads were putting on. Looked like a real satin finish and it didn't seem like there was enough tooth to it.
 
Well my 60 grit AO showed up today and it looks like it's going to work great!

You could almost harden a bit of steel and then blast it with this and use it for a nail file. I think the glue will stick as good as it possibly can with this method.
