After having a little bit of chain suck and other marks on my 456 I thought I’d do my old trick and use some inner tube to make chainstay protection. Without painting over the marks. Yesterday I thought I’d take the inner strip off to replace it and discovered some bits of rust that wouldn’t look out of place on an archeological dig. Panic ensued.
After calming down I took stock. I sanded off the rust and polished the living daylights out of the bare metal with autosol. It was then pretty much perfectly smooth, but with dark discoloured spots. Not pitted as such, more tarnished.
So anyway, I have removed the rust and painted over the bare metal with two coats of car touch up paint. I think this is probably going to be fine, but is anyone out there able to offer some reassurance?
My initial reaction when I saw it was “shit, I could probably poke a hole in that with my fingernail”. However, after cleaning it up, I am fairly convinced it was mostly superficial. I reckon the tubes are thicker walled around the bb welds as well(?)
And yes, I am a pillock for contriving to keep water in contact with bare steel on my prized frame.
