Here is a photo of a mahagony neck after Z-poxy. This spot looks like maybe some residual glue, but I sanded it thoughly before I put on the Z-poxy. I'm kind of afraid that if I try to sand it out I'll get witness lines or a different color from the rest of the neck. Does anybody know what this is and what to do?

I had that happen at the heel of a mahogany neck using the Stew Mac brush on Varnish and clear poor filler. I sanded it back to new wood and it didn't help. I ended up with the same splotchy look. I tintied some of the varnish to cover it.

It looks like it could be glue.
But you have some lines on the back of the neck that have the same appearance.
Which could mean it's grain coloring .
What finish are you using?
Is the humidity high 55%+ were your doing the work ?

I got those marks on my last neck, where I glued on ears to the sides. One right where yours is and one one the other side, at the end. I sanded one off. the other is deep. I think when I glued on the ears, the glue was absorbed into the wood. I don't remember ever wiping any glue on those areas. I painted the area with stain till it was close in color. basicly same as John.

-To me it appears to be glue which has been absorbed into end-grain. If that's so, it may be difficult to remove. CW

Thanks for the replies. This picture was after one coat of Z-poxy. I took a razor blade and scraped the spot, sanded smooth, and put on another coat. ...No more spot!
