Gary, If the edges are wearing through, I'd suggest a lacquer pen, or thinning some S&S black and using an artist brush, very carefully painting it on. One thing to keep in mind with edges is that the exposed area is only the obvious part of the problem. The finish is dangerously thin right next to the worn through area. If you try and apply lacquer thinking you can sand and rub it out, I'd warn you that you're likely to burn through again - the problem just keeps getting bigger. I'd paint on thin lacquer with no intention of anything other than rubbing with 0000 steel wool to take the shine off. William R.
