No easy cure - had the same thing on my burl door wood panels on 560sel. You have 2 choices:
1) get a replacement piece new or used (easiest)
2) send the piece away and get it professionally refinished (expensive)
Unfortunately those are your two choices. Refinish the piece yourself? Don't even think it. The coating on mine was tuffer than steel - you need a pro to remove it without damaging the wood underneath. Don't ask how I know!!
