Anybody know of any good ways to replicate nicotine staining prior to lacquering?

My initial idea didnt work.

Food colouring. Tremendously quick too.

Im spraying the nitro tomorrow so it should be good to go in a couple of weeks. Will spraying compressed air over the hardend lacquer craze it?

Funny...I was just talking to somebody about staining or tinting.

This guy said, depending on the finish, that standard Earl Gray tea works great for a little aging. He said to mix the strength of the tea to accomodate the darkness you are trying to achieve. Paint or sponge it on and leave it on for a period of time.

I suppose different tea's could produce different colors...more red or more yellow or brown...black.

Just clear nitrocellulose. I'm only going very thin with the lacquer. 2 coats max all i want it for is some minor crazing. I've stained over the top of the paint

Its about minus 2c outside and 26c in my kitchen. That could be a easier way to do it.

Thats going to be difficult. Im spraying from a can. Maybe theres some point at which i can intercept the hardening process and add it then.
