Bit excessive honestly. One panel needing a respray ain't that deep, happens to everyone. Paints got more leeway than people give it credit for.

Oh man, the "15 year old Shimano chain" part really got me. I actually just read a thing on another forum where a guy tested cheap vs name brand chains and the cheap ones wore out his cassette and chainrings way faster too. So you're not just buying more chains, you're killing other parts that cost way more to replace. Bill is right about that chain checker tool by the way, I got one after my mechanic yelled at me and it's wild how fast a cheap chain stretches. I've started just buying a mid range KMC or Shimano chain once a year and calling it good.

Foreman at my last site did the same thing with my corners. Hated it at first but now I'm way more consistent.
