wagner acrylic?

[Lisa Tomlinson]

Hello,
I was told that you may help me.  I am an accordionist from Vancouver,
Canada.  One of my accordions has scratched keys, with fairly deep
scratches made by long fingernails.
I was told that there exists an acrylic used to repair piano keyboards
called (and I am guessing) Richard Waagner Acrylic.
Do you know anything about it? Will it work on an accordion keyboard
with plastic coated keys?  What is the repair procedure?  How can the
color be matched?
I appreciate any input
Many Thanks
