removing paint from glass ?

[David _b]

Hi

I sprayed in a small patch on a sill on my car...however i guess i didnt mask off enough of the car because if you look very closely at the rear window there is dust size spots of paint on it. You would not notice it at all but its annoying me.

Does anybody know how to remove it ?

Thanks
