Keeping brass shiny

[CLP]

I'm building a case to display a cartridge collection (nothing collectible/antique), so I'm going to polish the cases with a polishing cloth. Is there anything I can apply after polishing to prevent them from ultimately tarnishing/oxidizing? I remember some guys in the army used to apply something to their brass after polishing, but I just bought the never-dull insignia which wasn't that much more expensive. I thought of Renaissance wax but I'm not sure if it'll completely seal it and prevent oxidation.

I'm not sure there is anything that is 100% effective forever.

Johnson's paste floor wax is cheap & good.

Coating with clear lacquer is better.

About 40 years ago we had a very ornate brass kerosene floor lamp professionally polished and coated with clear lacquer. It is still presentable, but has turned more brass color then the 'glittering gold' color it was when first done.

I have a grandfather clock I built in 1980 that has a brass pendulum, weight shells, and dial.
It was factory coated with some type of clear lacquer? And is still very much shiny brass color after 35 years.

think the aersolized laquer will apply the coat thinly? i think i'll give it a try.

Yes, lacquer is the way to go, BUT clean off any wax or polish that is on the brass before spraying. Mineral spirits and then polish with super fine steel wool or synthetic wool. Then spray before they start to tarnish.
