Re: New gearboxes - painted or bare alloy?

Hi Eric,

I'm ordering them new from Bonfiglioli Transmission in Auckland. They are 70:1 reduction gearboxes (VF44 P1 70:1 P63 B14).

So from a cosmetic standpoint you recommend paint? Is there any other noticeable or problematic degradation?

Does anyone know how long the paint lasts?

What make gearboxes are you using and where are you getting them?
If you leave the gearboxes unprotected they will look terrible in a short time.
I was considering having my gearboxes sand blasted and powder coated.
Any thoughts on that.

Hello everyone,

I'm ordering new gearboxes for the main furler and main outhaul. The units can be shipped with a bare alloy finish or with a 2 pot epoxy paint. I'm curious if anyone has advice one way or the other. The paint will provide protection but will undoubtly fail at some point. The aluminum alloy should self-passivate and not continually corrode/oxidize.

Any advice from experience? Any issues in running with bare alloy, besides initial appearance? I suppose it will look better than flaking paint in the long run.
