Iím ready to start the clear on my guitar. I went over the top with Stew Macs Lawrence-McFadden Grain Filler. The last guitar I built I also used it with good results for the most part. The one problem I had on the head a cloudy spot (about 1in. diameter) appeared after a couple weeks. I have never had this happen before. I used lacquer for the finish, the filler is oil base but they say itís compatible with lacquer. But Iím thinking ,maybe I had to much build up of filler wear the cloudy area is it might leached into the lacquer. So Iím thinking about putting coat or two of shellac on first before I start the lacquer. So any ideas of what the spot could be? I would rule out blushing Iíve had lacquer blush but always right away plus it was ideal weather. Another question do you think pr-mixed shellac would be alright to use?
