I live in Rochester (ok so it's technically Western NY) snd haven't heard of any, not even when I was living in Poughkeepsie, which is upstate.
I would check
Meguiars website out and see if they are doing something in your area.
Kleen Car Auto Appearance has classes all the time but they are in New Milford, NJ. Not sure how far that is from you.
