We have had good luck eliminating scratches in the polyurethane finish of the Sapelli interior wood using a "Fix It" pen (Simoniz). These are inexpensive repair pens that are marketed for fixing scratches in the clear coat finish of automobiles. They use a UV activated hardener--ambient daylight seems to work just fine--doesn't need to be direct sunlight. You can find these or similar products online and we have seen them in a few stores in the US. They work very well--making the scratch invisible and adding a durable coating layer. Try them on smaller scratches first--hopefully you don't have any really deep or large ones!
