Modern key tops

[Farrell]

I've replaced modern Yamaha keytops. A heat gun and a knife is all you need to remove - they practically fall off.

However, I agree with other suggestions for simply polishing the sanding scratches out. A good buffing wheel would do it in about 30 seconds (being careful to not heat the plastic too much). But if no shop tools, as someone else suggested, sand with finer grits and then use some sort of a hand polish. Plastic keytops polish up very nicely.

  G'Day fellow techs. Can anyone tell me how is the best way to remove damaged key tops from the modern piano i.e Kawai?
  I will need to travel a long way to repair one damaged key top on a K-18 model and will not have a workshop to assist me with bench tools. I do not like the idea of steaming, which would probably not work anyway, and knifing it off sounds pretty dangerous. 
  This problem was caused by some glue being left on the side of the key top, ( from the factory), then being sanded off to remove it, and subsequently removing the polish from the key. Customer needs all her keys to appear polished it seems!!
