Mark,
The lacquer on my guns lasts about two full hunting seasons. That is November through March. I strip the gun, then soak it in lacquer thinner. I then clean with a toothbrush as necessary. I hang the receiver and other parts from soft iron wire and spray with clear gloss lacquer. I start by spraying the topstrap with the lever to the right. I then release the lever and spray the rest of the receiver. Keep your coats light. You don't want to fill the engraving. If you scew up you can alway take it off with lacquer thinner. The whole process including stripping, cleaning, spraying, drying and reassembly takes about 2 hours. Remember to lightly lubricate the receiver prior to reassembly.
