Well, being this is a pearl particle...do not use any sandpapers....Try using some different scotch pads...this won't hurt the particle load, and will change the cover nicely...
Burgundy pad = 400
Green pad = 600
Grey pad = 800-900
White Pad = 1100
Start low and work back up to where you want...will also clean up the surface while doing so....do it that way, and you can't go wrong...can't hurt to try..
