I used 2k etch lacquer on mine .
I think the only other option is a clear powder coat maybe .
As for the shed adding a couple of vents helps for airflow .
Got any pics to put up so far ?
Still not quite finished mine . :facepalm:
Just got the front mech cable to put on and the chain needs a few links removed .
I haven't got to grips with putting pics on here yet.
A local powder coater did a good job on another frame , at the time he did suggest clear coat the bare metal, so I was thinking of giving him a call .
