Wait! Don't do anything!
Firstly, is it a flat paint? I've found that simply taking a toothpick, dulling down the point, and pushing at the edges of the paint spot will remove it with no ill-effects to the canopy glass. Once that's done, just polish the area and you'll never know there was any paint there! Just don't push too hard, you don't wanna crack the glass!
I just had a similar bit happen when I was freehanding the det-cord housings around my Apache windows. Just cleaned it right up with a toothpick and all was well!
