   That's called a "fat edge".  Usually results from too heavy a coat.  Sometimes exacerbated  by not breaking the arris, or edges of the wood slightly.  Finishes tend to pull away from sharp corners.

   Try thinner coats.

   Woodwiz,

   I'm brushing deft lacquer..after stain and two thin coats of shellac.  Do I need to be concerned with sharp edges too?  thanks

   I think it's always a good idea to break sharp edges.  I'm just talking about running a sanding block with 220 grit down the edge once or twice, not rounding or dubbing the edges.  Sharp edges are fragile and don't feel good to the hand, plus most finishes do tend to pull away from them.  I don't know for sure about Deft because I never have used it that way.

   Woodwiz,

   thanks, better safe than sorry...I'll hit it with a little 220

   This occurs to far away from the edge, 1/8 to 1/4 in. to be from a heavy coat. Any further ideas?

   My recommendation still stands.  Break any sharp edges and put on thinner coats, allowing the material to dry thoroughly between coats.  Reduce the thickness of your coats by about half.

   Also, make sure your material is thoroughly mixed.  The ball should rattle for a good two minutes by the clock, the first time you use it, and should be shaken every few minutes while you are using it.

   This will reduce the variables.  If that doesn't work, then we can look at other things.

   As a gratuitous aside, Deft is my second least favorite finish, after oil-based poly.  My preferences would be shellac, aerosol lacquer from Behlen or Mohawk, wiping varnish, oil-varnish blend, or just about  anything else.

   That's most likely your problem (sharp edges).  The advice is right, your coats are probably too heavy.  Use very light misting coats, keep your project between you and a light and watch the surface you're spraying.  When you start to see a slight sheen behind the spray, you're as heavy a you want to get.

   I'll attach a picture of the project. This began to occur after I sanded between caots with a "stearate" paper.  Is that the problem? It also occurs close to the edge banding, which is rounded over.

   Always spray your edges first, then back and forth, then back and forth perpendicular to those passes. Back off the trigger or button as you pass the edge. Trigger again before you pass over the work.

   Edges need more finish as they will get more wear.
