Patina is a lovely lady who wears her age well. I'm very fond of her and wouldn't change a thing about her.
But not all of us age as gracefully as she has, and I enjoy painting bikes. So I look for the bikes that are so badly chipped, scratched, faded, repainted or rusted that their former beauty has been, for the most part, lost. Lucky for me these are the bikes that people are most eager to be rid of.

But monetary value? That's another subject. Good quality automotive paint, decals, and good quality chrome work are not cheap. I usually break even; and that's only because I don't have to pay myself a wage.
