Question - how thick was the white applied - and HOW did you apply it (i.e. how many coats, and in how many "passes" per coat?). If it was applied in a single pass and/or too thickly that could have been the entire problem - and it would not have needed to be removed. The blobs/runs at the corners and ferrule holes tell me it was applied WAY too thickly - and all at once. That's totally wrong. EVERYTHING sprayed should be applied in thin coats consisting of 3 VERY thin passes per coat. A single pass should be very transparent, and a single coat should not fully cover by itself. If either does - it's too thick! And apply everything - the entire system, to completion - on a piece of scrap BEFORE you start on a body if you have not used even one of the components before. That is how you recognize - and solve - preparation problems, product incompatibility, thickness issues, environmental problems, technique issues, finish sanding problems, get your questions answered *ahead of time* etc. It's how "what happened to my guitar?" threads are avoided..some of which are "no-return"... and useful, "what is this problem on this piece of scrap wood?" threads are created. And how a lot of money is saved.
