I was looking at the binding sand through oo4.jpeg and a clear lacquer touchup marker came to mind. http://www.stewmac.com/shop/Finishing_s ... rkers.html
You could probably do the same thing with a touch up brush, but the pen can put down a thin even layer of lacquer.

It is basically a felt pen with clear lacquer. It will not fill but on the edge of the purfling you can easily touch it up. I waited a couple of days after I drop filled before I scraped it. I am not sure if that is too long or too short but it worked out for me.

My local woodworking shops Rocklier and Woodcrafter has Behlen blush eraser.
BLUSH ERASER®
Humid or cold weather can cause a finish to
turn white or “blush”. Behlen Blush Eraser
reflows the lacquer and allows the trapped
moisture to escape. 13 oz. can.

I did use Z-Poxy, so that may very well be what's happening. I think I may try the lacquer felt pen thingie on all of the spots and see what happens.

Carefull, there is real lacquer in the pen so once you apply it leave it as it will have softened the lacquer around where you applied. Play with the pen on some wood to get a feeling for how and when it comes out. I learned all of this with a sunburst three colors deep. A sunburst that I re did three times learning about lacquer.

Bingo on the white spots using expoxy filler...I have had this happen a little on 3 guitars.....thus no more epoxy pore filling for this boy.
David, on the sand throughs, lay so paper over the guitar around the area and lightly spray some lacquer over it, being careful not to creat a "line" or ridge of lacquer where the paper is, just blend it in. Do 3 or 4 coats, then resand and polish the area. You can do this on the binding edge too. It is not as scary as it sounds, but you will need to wait 3 or 4 days for the lacquer to harden up again.

Are the white spots you are talking about an adhesion problem between the epoxy and the nitro?

I can't really tell if this is what is happening or if it is something else. The best way that I can describe it is that it looks like a dull spot, that for some reason it didn't polish out with the rest of the surface. That is what it looks like but I don't think that is what is happening because it doesn't make any sense, with all of the careful surface prep that I did starting with bare wood all the way through the multiple coats of lacquer, I don't believe that there could be a low spot, so low that my rubber faced sanding block could not have dipped down enough to buff out. Logic tells me that it is either an adhesion problem or possibly a partial sand through just to the Z-Poxy filler or possibly (but less likely) some trapped moisture.

John,
I don't see that on Davids guitar, but I have had that happen on mine...teenie tiny speckles, but they are white. It is either a reaction or adhesion, don't know. So far no lacquer has flaked or otherwise come off of any of the three guitars, and these spots are pretty hard to detect unless you're really looking close, but I don't want anymore of them, so I'm leaving epoxy behind just incase it is the cause.

Righto Kevin, no whiteness at all, just dull, as in not shiny!

I really have no idea what I am talking about, but that has never stopped me, but when I think dull I think defraction of light. The dull was why I was thinking of an adhesion problem right at the dull area. There might be enough of a gap that there is a bit of defraction of light and the wood does not read through so well. For example if you lay some scotch tape on wood, it looks dull. When if you press it down the wood reads through and you see the shine.
Just a thought

I get what you are saying and although that (and anything else) is possible, I think the best candidate so for is partial sand through, just to the pore filler, not quite to the wood, but I don't really know what I'm talking about either so I'm trying to keep an open mind.
