I've got a project Murray Monterey (my RRBBO bike) that I stripped the paint off of and I want to protect the raw frame and the rust/patina. Is a simple clear coat the best way or should I think of some sort of wax or even polyeurathane? Basically I want the frame to have a wet, polished look without getting rid of the rust. The rust when wet really "pops" and i want to keep that look under a finish. Any ideas?
