Post subject:  Nitro Lacquer Recommendation
Just like the title says : I have been using Mohawk Stringed Instrument Clear Lacquer for years but I'm looking for something that has little to no UV Inhibitors and Plasticizers.
Can anyone steer me in the right direction ?

No plasticizers? Are you looking for lacquers that craze?
I can't help you as I don't know each manufactures formulas.
I do believe you can tint the lacquer and craze it with a can of air though. Dan Erlewine finishing books may cover this, I,m not sure.
Sorry I'm not much help, just curious as to why you wouldn't want any plasticizers in your finish, I'd think it would be really brittle with out them.

You might try Deft or Minwax brushing lacquer (home depot?).

Talk to an expert at Sherwin Williams. Note, I said expert. You have to look closely at who you talk to there, sometimes, the help there doesn't know one paint from another. But find the right rep or manager that knows their products well and you'll find what you need.

Yes...and with no UV inhibitors it will allow to aniline dyes to nicely fade

Mohawk Piano is working for me John Arnold recommended it over the instrument lacquer.

Piano Lacquer
M610-130 (90 Sheen Gloss) Available in 1 gallon, 5 gallons
Mohawk Finishing Products Division of RPM Wood Finishes Group, Inc.
Product Data Sheet
Product Description: Mohawk Piano Lacquer is a high quality nitrocellulose resin blend specially designed to allow higher build without sacrificing clarity for piano finishing and refinishing projects. Nitrocellulose coatings are the preferred material for the piano and musical instrument industry because of its clarity and rubbing properties. Mohawk Piano Lacquer’s blended formulation enhances these expectations by providing a harder more durable film that can be built to a full 7 dry mils and buffs to a higher sheen while maintaining excellent clarity.
Use Piano Lacquer where a heavier than normal film build is desired on surfaces intended to be polished to a high gloss. Piano Lacquer is ideal for high end finishes where high build and clarity are a must.
Advantages:
1. Formulated for high build applications up to 7 dry mils
2. Excellent rubbing clarity
3. Conventional VOC formulation
4. Can be sprayed HVLP, conventional high or low pressure or electro-statically
5. Ready to spray in high gloss 90 sheen, can be heated to 100o F for hot spray
6. Yields harder finish than Classic Instrument Lacquer for added durability

I don't think you will find it. I have looked and have concluded you would need to brew your own from complete scratch as all the base stock whetted nitro chips available in the US are made by DOW and heavily modified with a soy emulsifier as a plasticizer......NC Nobel base stock was the good old fashioned stuff but they no longer import it to the US.

Sherwin-Williams used to sell (and may still sell) a lacquer called ProMar Hi-Bild B44. It was not even on their website but my local SW store had it on a back shelf. It is about as old school as nitro comes. A local electric builder uses it when he wants a relic finish. It is very hard and if plasticizers are in the mix it is a small percentage.
