Help, Iím having a hard time getting the finish to work on the ebony headstock. I am spraying Lacquer (Deft) directly onto the wood without issues excerpt on the headstock, where I keep finding small bubbles in the finish. Is this common? The bubbles donít seem to appear anywhere else, only on the ebony. The bubbles donít seam obvious when applying the thin coats of lacquer but appear when Iím leveling (wet sanding). Another variable perhaps worth mentioning is that I have been laying the mando in my work space near a 60W work lamp to help with drying and discourage humidity. Not optimal Iím sure, but again the bubbles are only showing up in the ebony. Perhaps I need to apply a sealer coat to the ebony before applying the lacquer. This is now the second time that I have had to strip the headstock back down to bear wood. Your help/suggestions would greatly be appreciated.
