Hi Ken, Lacquer thinner will do just fine. As it happened, when I read your post I was in a practice room with a Yamaha G-2 with a nice white paint smear on the lid. Wouldn't budge when I tried removing with fingernail. So I experimented for you. After using the lacquer thinner, it looked fine compared to the rest of the piano. I then used a bit of Flitz and polished. Now it looks better than the rest of the piano (like new - the rest is scratched and dirty comparatively). But bottom line: lacquer thinner won't touch polyester, and it will remove just any wall paint, whether scraped on or actually applied wet (as in paint drips from not covering the piano.
