CA white isn’t close to Alpine White. Plus, white poly finishes all seem to have black right below the surface, so that always shows through. So, doesn’t look perfect, but the chip and hole are filled, flush, and polished.
The bigger issue is what I thought was a big shim at the pocket heel is just the way the pocket was cut. So, even after following John Carruther’s setup videos I have significant buzz starting at the 12th fret. The only solution was to raise the bridge and end up with high strings from the 3rd to 9th fret.
