I'm taking a short break from pinball tinkering to get this Brass cash register restored. It's been on my to-do list for 4 years now. I'm excited to get her done. I'm going to mirror polish the bronze case but I don't want the maintenance. To keep it shiny it needs to be cleaned with brasso once a week...... forever. No thank you. My plan was to use the 2k rattle cans to clear it but I read that I shouldn't. Lots of sources online say I should not put a lacquer clear on antique brass but no one ever says why. Does anyone here have any experience with this? Does 2k clear have any lacquer in it? Know a better way to keep the shine? I'm all ears.

The brass substrate will continue to oxidize beneath the clear.

Never messed with it but my first instinct would be to polish and then wax which should keep the shine

Quoted from Rody:

Why is this? Is the clear porous allowing air to reach the metal? Does the clear itself oxidize the brass? I don't disagree with you. I keep reading the same thing but I can't seem to find out why.

A regular waxing will also be a never ending pita. Getting the wax out of all the nooks and crannies is not how I want to spend my time. I'm looking for a no to very little maintenance solution.
Id also like to know how the brass will continue to oxidize while covered with a 2pac.

Ive had insane success with this product on brass, copper, gold, silver, aluminum, playfields...

Its a self leveling, self evaporative coating that cleans with alcohol

Polished brass has no mechanical tooth for urethane clear to adhere to, therefore it is subject to separation from the substrate, which then leads to oxidation, or clouding. I use ceramic, air dry clear, from Cerakote, for all polished metal products coming out of the paint booth. Ceramic particles do a better job of adhearing at the molecular level to polished metals than a standard urethane clear will.
