I'm finishing a new neck (manufactured, not scratch) for one of my LP-style guitars with a bolt-on neck. It has single binding along the fretboard, and 4 layer binding around the headstock.
Last week I masked it all off very neatly and applied my stain (Feast Watson PF - alcohol based). Masking worked pretty well, but naturally still had a some clean up to do. I got it all nicely scraped without too much effort. Due to weather, schedule etc, it sat for 5 days or so.
Fast forward to today and I had the opportunity to spray my poly. I used my usual 60/40 poly/turps mixture and got my first coats on. Then I noticed the stain was bleeding onto the binding. I've only sprayed stained necks with binding a couple times before, but never had this happen.
I still had a bit in the pot, so I decided I'd spray one more coat, leave it to set, re-scrape the binding and then re-spray the edge (maybe with just my airbrush). My thinking being that once the initial coats of poly are set, the stain will be stabilised with it.
Prior to spraying the poly, I gave the neck a good wipe down with a clean dry rag to remove any dust and also check the colour fastness. The rag came away with hardly a tint of the stain on it. (I didn't use a sanding pad as I didn't want to affect the depth of colour).
Should be an easy fix, just an extra step I didn't plan on. Just sharing in case anyone else has had this happen...
