If you guys are doing barrels then why not invest in a bolt similar to the ones in the 2 piece wheels, put that in a hole and hang them that way, Where i powdercoat well use a rewire and tie it to a Washer then stick the wire through the valve stem hole this way you only have a small area instead of handprints. It does seem like the guy complaining is investing his money in wheels to sit on a shelf instead of put tires on because that is the only reason i can think of why hes complaining about something that isnt seen, But id try using a thin piece of rod or a bolt similar to the ones used to keep the wheels together and then hang it by a bolt from there, thats what ive done for the sets ive done and it seems to work perfectly and not leave but a tiny mark that will be covered by a bolt as opposed the barrel.
he would probably complain about that to.
i use a threaded rod through the valve stem hole with a nut on the front and washer/nut on the back. problem is they are heavy and you can't avoid touching the wheel to lift it into the oven and get it on the rack, unless you have a rolling rack and just shoot them hanging and push the rack in
I think next yr im buying a powder booth and 4x4x6 oven. I want to venture into other stuff than car wheels. I think im going to build a custom motorcycle in my spare time and do all of it in powder. I just bought a bmx frame to build to so I can show that off whenever I go to places and set up.
A lot of people don't realize you can do stuff like that, they thought it was for like car parts and stuff.
