It sounds like a mild case of OCP, but how much did you pay for that new paint brush and is its sole future intended use to clean welds? Are you contemplating a matching outfit for this bike? Including new carbon soled shoes? Would uber-light carbon wheels make it a better/faster ride? Do you mostly hang-out with the bike at the local coffee shop? You just might be .... OCP.
