Andrew,

>Here is the problem, the film thickness is certainly more than 0.6mm.

Sorry Andrew, I have come onto this thread late in the event (been 
distracted with work). From what you've written I conclude that the 
piano you have a problem with is a Yamaha. I too have seen Yamaha's 
with a film thickness of more than 0.6 mm, but it is the exception 
rather than the rule in the case of Yamaha (0.6 mm is Yamaha's 
factory spec.)

I'd say it will. If its cracking up I'd get rid of it.

>So maybe a heat gun will be my newest toy.

We struggled for many years with unsatisfactory approaches to 
stripping polyester. The heat gun approach was a revelation. Be 
careful with it and the scraper and you can do a good quick job 
without damaging the veneer.

Regards,

Ron O.
