I used Nikolas 2105 air-dry. I also use Egyptian if I do a full horn. Both nitrocellulose lacquers airdry. I get too many compliments on how much more open horns seem to play with nitro. There are so many reasons that I am not interested in baked finishes. I used to spay them back in the 80's at a different shop I was in. Never cared for how they flowed out. All this said, overly thinned nitro or the canned stuff will not last real long. 50/50 or 60/40 lacquer to thinner works well with good longevity. It does darken with age. I have examples that have held up so well for 15 to 25 years. I have also hsd horns that I sent out for 2 part baked that have not weathered all that well for the hype. All finishes are temporary in nature. Silver plate and nickel plate are among the most long-lasting and least temporary. All lacquers are more subject to elements like sweat, salts, low and high ph. But lacquers are oh so pretty.
