So should I paint, or leave it as is for that rat bike look?
What I find after peeling off a black sticker... dang rust. Dang uncle for just hanging it outside.
Keep the rat rot look, throw on some flatbars and make it look like an old racer.
"the bus came by and I got on, that's when it all began...there was Cowboy Neal at the wheel of a bus to never-ever land."
I say go for uniformity, whatever that might be.
Strip the paint and let the whole frame get a nice rust patina
or flat black / Rustoleum it.
always keep a rat in the garage!!!! fast eddie outty
If the paint is original don't paint it. If it's not, go for it.
