There’s a raw finish on the 456 Evo.
I think they sum it up well…
Note :: Raw Finish is designed to have manufacturing blemishes and might not appeal to all. Also, it’s extremely likely that some degree of surface rusting may appear in time, though due to the only process that this frame has been through is the first surface treatment in the paint process, the action of that rust on the frame is only as bad as the action of rust on the inside of a painted frame. The frame is coated with a matt laquer, which being slightly porous will allow the steel tubes to corrode, but this, we consider, gives a patina of age and wear (like a nice wok) rather than it being a problem.
If you have an issue with this, please select the painted option.
456 linky for completeness…
