That is precisely the way I would have done it, but I have come to understand that the previous owner was under the impression that "restoration" included the metalwork. BTW, I am building this for a friend. Once finished, it should be a real nice looking machine. AS in the case you cite, the local frame-maker here does not do his own paintwork. He couriers his frames hundreds of Kms south to Osaka to have them painted. Of course they are all prepped and ready.
It is a shame that, in your case, the frame work wasn't done before the paint, but that's the way it goes sometimes.
