All other media must be da'ed with 80.
I then asked him if crushed glass was acceptable as well and he said yes.
Barry is a really good guy BTW. I owe him a lot.

I'm surprised he said crushed glass, that doesn't create a tooth, it creates dimples. Cerakote requires aluminum oxide to create a tooth and they say precisely not to use glass because it leaves a dimpled surface.
And I like a blasted surface because it gets everywhere, especially in little nooks and crannies that nothing else can, and in seams, an important place for adhesion.
