Yeah it's definitely dirty on the backside. I could have a reasonable crack at cleaning the inside of the tube because there's access via the BB shell. So I could get busy with a ball of wire wool on a coat hanger with some Kurust and then repeat with some alcohol.
But yeah if you tell me it's likely to fail even given that prep then I'll take your advice and go to Winston.
I also had ideas to just lay up some carbon weave over the stay (I've repaired carbon frames before) but that feels more like a bodge at this point.
@Biggles567 Thanks for offering and for the info.
