Thread: Rust Prevention

Very interesting indeed but installing zinc washers that are meant to sacrificially corrode, even on a minute scale, has some problems. Firstly, corrosion. Over time the washers will change shape, a very small amount but still change. Second, zinc oxide. Not as hard as iron or chromium, but still a grit that is going to wear everything it upbraids against.
I still see regular maintenance as the best choice. Drying and lubrication. If you're in a more challenging atmosphere, add some Tuf Glide:
"Sentry Solution's concept is simple - dirt will not stick to equipment lubricated with a dry film and metal surfaces protected by a dry micro-bonded shield will not corrode!"
