Get finishing book by Bob Flexner. I believe by Taunton press. It will detail how to determine what finish is on the cabinets and what finishes are compatable.
Cabinet finish.....
I have a a pair of Teledyne AR-9 towers that are in perfect working order, and the cabinets are a solid 8-9 in rating but I want to gloss the finish up a bit, what can be used with good results to get a nice rich semi-gloss to glossy effect? thanks Chad
