I'm building a steam engine right now from a casting kit. I've gone FAR overboard: hand scraping the iron castings, grinding and polishing the brass castings, using PPG direct gloss automotive three part paint.
My question is this: how can I keep the polished brass parts looking good for as long as possible? I don't like the idea of sprayed coatings (e.g. Nyalic, lacquer, etc) as it's a PITA to apply and takes away from the shine.
This engine is being built to be show quality and will never see UV rays, salt water, etc. Just the occasional fingerprint. But, it will be handled and used...
Any ideas? Right now I'm trying car wax as a test.
