[CAUT] Paint on Polyester

[John Ross]

Paint on PolyesterIs it possible, that it is not white paint, but just an abrasion on the polyester?
If it is an abrasion, it can be buffed out.
Come to think of it, if it is white paint, it can be scraped/sanded off, then buffed.
Polyester is quite thick.

  Subject: [CAUT] Paint on Polyester


  We have a Yamaha C3 (black polyester) here that has been in a practice room for several years, and was just moved to a classroom.  There are some spots/streaks of white paint on the edge of the lid, from the wall of the PR.  I have no idea how long it has been there.  It looks like it happened the last time the PR was painted; I don't think it is from being jammed up against the wall.  Scraping the paint with my fingernail had no effect whatsoever.  Since the piano is now in a classroom, where everybody can see the paint spots, the boss wants it cleaned up.  I know poly is pretty inert, but I didn't want to just start trying solvents.  Anybody have any experience with this?  What will remove paint but leave poly alone?

  Thanks,
  Ken Z.
