Well at least he's consistent Don? I had my 350F tank painted by a local panel shop in '96, it took them 3 goes before they got it right, and I don't think they ever did another bike tank after mine. They brought it to me (at the gas station where I worked part time) with runs, the first time, then they dropped it and folded one corner in. The last time it looked great and was well worth the money, but it was lucky that I had a spare tank so I could ride it while I was waiting.
There was a clown in the US selling CB750 "Paint sets" and the guy who imported a one owner (but rusty) K1 had me install the "tins" as part of the bike's preparation to go back on the road. I gave the thing a service, installed a Dyna 2000 ignition, cleaned and rebuilt the carbs and it went like a new bike, maybe the best I'd seen of an old bike brought back from sitting so long. Last thing I did was install the new "tins", and didn't start it until he came to collect it. There must have been good fuel in the float bowls because it started and ran like a champ, and he was happy. We loaded it on the trailer and off he went.
A few days later he rang me to say it was running like #$%*. I told him to drop a float bowl to make sure there was no crap that had transferred from the recently repainted tank, and yep, the carbs were full of blasting grit. He kept asking me to fix it, but I told him how to do it himself, he was a cheap-arse and would have expected me to do it for cheap, if not for free.
