Hi everyone, I've started to research different methods to prevent brass clock components from tarnishing, specifically the plates, bridges and non-functional surfaces of wheels. There appear to be two main methods; applying a clear lacquer or using a carnauba wax after polishing. I guess every experienced clockmaker has their preferred method, but I was wondering if any forum members would mind sharing their preferences and advice. Regarding carnuaba wax, there are two brands that come up on internet searches; W R. Smiths Rub N Brite, and Clockshine Carnauba wax. Does anyone have experience with either of these brands? In terms of lacquers, are their any specific brands that anyone can recommend? I guess the three main questions for me are: 1) Do waxes and lacquers have a detrimental effect on oil if the oil sinks are waxed/lacquered? 2) Is there any specific preparation or process for either waxing or lacquering that will achieve the best result? (for example mix lacquer 50/50 with thinners, use a hair dryer or heat gun to assist the drying, etc?) 3) If lacquering is preferred, is there a specific type of commercial lacquer (or specialist clockmaking lacquer) that are recommended? There appear to be a lot of commercial brass lacquers, however, these lacquers appear to be used on household ornamental objects. My concern is, are they actually suitable for a functional mechanical clock? I'm really new to this, but if any of you have a tried and tested method, I'd really appreciate your advice. Finally, If you have tried both lacquers and waxes, and have a strong preference for one over the other, would you mind sharing your reasons? I hope this post creates some interest, as I'm certain every clockmaker has faced this question at some point. Best wishes in the meantime, Paul.
