Roughing playing surface?

[Swamp]

What grit sand paper do you use to scratch your glass playing surface?

I usually use around 80 and then switch to a stone to smooth it down a bit.

If your talking about glass that hasn't been conditioned yet then I hit it with Amour etch followed by a stone to smooth it.

I precondition all my glass with Armor Etch before I build the call. If you are talking about a call already built, I would use a stone to start, then 150grit to finish
