I have a Suntour LeTech derailleur. Like a lot of the derailleurs that have the names and branding screened on- the screening is starting to wear off; despite having REALLY low miles on it.
I would kind of like to use this derailleur, however I don't want to damage the screening any further (and truth be told, it might actually be more susceptible to wear in a box or even wrapped up than it would on a bike).
Has anyone tried any sort of protective coating over the face of a derailleur or something like that?
I thought of using clear nail polish. It's clear, relatively tough, a lot of people use nail polish to touch up bike finishes and it does come off with nail polish remover. I don't know if the clear would turn yellow or if it would eat the screening- but I decided to test it out on a Suntour AR. The AR FD has been through a bunch of bikes- it was on my sister's bike, and I've had it on 2 different bikes. The Suntour and AR screen is still quite intact. So I brushed some clear nail polish over the screening. I did this last night- and it doesn't seem to have faded the ink, and it doesn't appear to have dulled the chrome- if you look close you can see where it was brushed on.
Of course, who knows how this'll hold out over the long haul. I'd imagine it might take the screening off if you would ever choose to remove the clear, or the polish remover would also remove the screening ink.
Anyway- it's just an idea.
