91% is the strongest I've seen and it is what I buy.

I use 99% as that's what I can get cheaply at an electronics store.

I have been running 70% drug store stuff through airbrushes with Tamiya, Poly Scale (back in the old old days), Model Master Acryl, and Gunze for 25+yrs and had no troubles.

I use 91% from Wal-Mart or the drug store.
