I saw a few older forums on the use of Nikolas 2105 Gold-tint Spray lacquer. Most of the comments were how good the results looked, but I would like to get feedback from the people who have used the spray lacquer and get insight into opinions of 1. "How was the playability and sound impacted?" and 2. "How long did the lacquer stay intact on the trumpet?" Curious, I am considering using the process on my C trumpet and a Bb Trumpet which both are in raw brass currently. Thanks for any insights to your experiences with Nikolas 2105 Gold-tint Spray Lacquer.
