clear coat question
i just finished building up an old steel frame into a fixie. it has it's original coat on it, but has spots of rust in a few places. i like the weathered look, so i don't want to paint it.
here's my question: should i clearcoat over it to prevent the rust from getting worse? i was thinking maybe use framesaver, in addition to clearcoating as a means of preventing the rust from getting worse. is this excessive?

Be sure to minimize and treat the rusted areas before doing any sealers such as clearcoat. I would take a small wire brush(like a welder would use) and brush the rust down to mostly bare metal if the areas are more than a spot or two. Put on a little Extend to convert and inert the rust into a black primer. Match the paint to whatever you choose, then if you choose to clearcoat it, prepare the whole thing.
To get clearcoat to adhere consistently, you should wipe the entire thing down with a cleaning solvent such as acetone or finalwash. Scuff all gloss off with a scotchbrite pad and tack-rag the dust off. Apply the clear and enjoy.
My personal reccomendation for cost-effectiveness, since you stated you are not out for show quality gloss, is to simply treat the areas, touch them up apropriately and let them dry thoroghly. Next, seal it all off with 2 liberal coats of carnauba wax on the outside and framesaver/extend applied to the inside of the tubing.
Wax is the best freind of a steel frame. It looks good, keeps mud from sticking and seals water out.

I have treated such project by sanding off the rust and feathering the surrounding area. I tape off above and below the prepped area (usually a few inches or so), prime and paint a contrasting and/or complimentary color. I then wax the whole thing and hope for the best.
As an ex/old Sailor I don't like rust. There is NO WAY to stop more rust by clear coating over rust/bare metal. At least that is my experience, and I've tried some pretty shady snizzle in my day.
