Question
Once I have sprayed lacquer, and it has blushed, what can I do to fix it? This is an aircraft quality lacquer and the directions recommend mixing 1:1 with thinner. I have been spraying a non-tautening dope, but the customer switched to tautening (because he did not want to wait for 3 weeks for the non- taut). I mixed 2000ml NC with 1600ml thinner, and 400ml retarder. I understand this to be 10% retarder, right? It did blush. Do I spray another coat with more retarder, hoping to release the trapped moisture? I am not concerned about being too glossy, but I do not want to have a soft finish.

From contributor D:
You could spray another coat with more retarder, but be careful about achieving too thick of a final coat. Some NC lacquers have low mil tolerances. With NC lacquer I have never used retarder in the initial coats. If I run into blushing, I spray a very light coat of 60 - 75% thinner and 40 - 25% retarder, no lacquer. This usually does the trick without adding more material to the surface. I also do this to fix minor fisheye and orange peel problems and to get my high gloss topcoats to lay down as much as possible before I start the buffing and rubbing. After I spray it, I move it to a dust free corner and move on to the next piece.
