We live in a Class A Tradewinds motorhome built by National RV of Perris, CA, now closed due to bankruptcy.  The cabinet work is beautiful raised panel Walnut with a satan finish.  We have some scratches and dull spots, and we’re trying to figure out how to bring them back to uniform finish.  The unit is 10 years old and we have lived in it full time since the Spring of 2004.  Any thoughts on this would be appreciated.  Thanks!
