It was raw, really worried it would rust so I grabbed the first can I could find and went mad, turned out to be red and I hate red so I found a blue one but it ran out :)
It'll go off to armourtex for a single coat of something next time I get payed.
Don't worry about rust. The steel needs to be prepped anyway. Either it will be blasted or sanded before paint. It needs to be really bad rust to not be good looking paint once finished. If you go to Talbot or other frame builders you'll se rusty frames hang around the shop waiting to be painted.
Similar build, similar problems. Frame built with Zona tubes on the framebuilding course. Couldn't decide on the paint and just left it raw. Rust is just superficial now, won't be a problem removing it before the proper paintjob.
omg that paint, whhhyyy
