Had the bowling alley finish on a 28 that needed a good clean up..stuff cuts right through it with ease and it scrapes off like it's nothing using a couple pcs of plastic (Delrin) ground up to a scraper/knife edge ..a belt or disc sander to keep the scrapers edge touched up is a must..follow with denatured alcohol to expose any spots missed.
Medallion should come through your refinish unscathed...avoid it w/fine sandpaper as it will shine up unpleasantly w/an uneven finish..scotchbrite will restore it to a nice even finish should you get a little sloppy with sandpaper but go easy as it doesn't take much.
