So, I found out something pretty interesting today. Turnbull does not use lacquer but, a shellac based varnish that is not sprayed but, wiped on. They were using Behlen's Violin Varnish that is basically a blonde shellac and gum additives. Mohawk dropped it from their line once they purchased the company. I am floored that is not a lacquer and that it is wiped on. It looks absolutely flawless when they do it. They said that straight blonde #1 shellac could be used as a substitute but, I don't think that would be as durable as a clear lacquer.
The ideal grade L.C. Smith has some deep relief engraving so, wiping it is out of the question. I will definitely be spraying the lacquer. I do not know if I will use a touch up gun fed by an air brush compressor or a regular gun fed by my upright compressor. Lacquer is supposedly very easy to apply. Here is a great link to another forum where they are discussing applying lacquer to smaller pieces. I found it pretty interesting.
