x) The phrase "frame off restoration" means nothing. Sounds good, means nothing.
y) While we're on #27, what you're doing is not restoration. What Jim Cunningham does at Cycleart is restoration. Spraying the bike with clearcoat, the tires with hairspray, and doing a minor overhaul is not "restoration". It's primping the bike for sale.
z) And if you spray the frame with clearcoat, the tires with hairspray, and perform a minor overhaul, it doesn't magically make a 20$ Free Spirit worth 300$. It's still worth 20$.
z1) Rattlecan paint jobs are not really paint jobs. And spraying over the Huffy, Free Spirit, or other gas pipe name brand does not magically make it worth more. The magic in that can of Krylon is limited.

Inspired by our local Craigslist, I thought I'd add in these.
