Re: New gearboxes - painted or bare alloy?

Mike,

I would choose the paint.  The gearboxes are likely made from cast aluminum which tends to oxidize much faster than extruded aluminum does.  It also gets that unsightly white, chalky, aluminum oxide powder on it, not a nice uniform oxide coating.

If you go with the bare aluminum you will need to clean it regularly to keep it looking nice.  If you go with paint, you won't need to do any real regular maintenance other than fresh water rinsing until the paint fails.  At which time you can remove the paint, re-paint it and begin the cycle again or leave it as bare aluminum for awhile, see what happens, and decide what to do from there.
