That's a really nice subtle shade of brown, great finish too, seems to have some shine. Looks perfect in the pics. Is that spray-on or brush-on Rusto? Love the thumb shif-ters, I wish Shimano would start making those again, as it is they're practically worth their weight in gold.
I have lots more fun with projects like this than buying something brand new. My problem is, I never know when I'm "done", so at some point, the bike eventually winds up in pieces again.
It really takes some extreme discipline to restrain myself from making more changes, or putting the parts onto another frame I think will be "more better". But hey, it's my stuff, and I paid for it, so why not?
