Its been a while since I've posted here, I took a long break from building guitars to do a few amps and cabs. Everything was going great with this tele until I sprayed lacquer. Here are some details: One piece double ABS bound mahogany body, sanded to 400 then rubbed on a light coat of tru-oil. Waited three days. Next spread some thin CA glue around to fill the grain. Waited one to two days. Scraped away excess with cabinet scraper and sanded to 400. Applied another really light coat of tru-oil. Waited 3 days. Light sand to 400. Sprayed Behlens Qualalacq mixed with a drop each of Transtint brown and amber. Instantly this spot appeared. I used a preval to spray. Its 57 degrees, 45% humidity. Body was room temp and lacquer was warmed a little by hot water. The tru-oil is old, dark, and thick. It was also applied to the neck before spraying and that has no issues. I've never used CA glue to grain fill, but it seemed to work great. The card scraper made removal very quick and easy. I usually use an HVLP system but my compressor is out of commission. I sprayed the maple neck and maple pickups at the same time with no issues at all. Thanks in advance for any insight.
