Polishing hard lines

Recommended Posts

What are people doing to polish the various hard lines like fuel & brake lines?

I've just been clamping the tube in a vise and sanding & polishing it lengthwise. First some 800 then 1000 grit sand paper, then fine steel wool and then some metal polish.

The plating is so thin that it is easier to buy/fab new tubing. There was a post RE finishing of brake lines a while back.

Think the polishing might be short lived if you go too far. A paste polish compound would be better and remove minimal plating.

Unless the tubing is aluminum or stainless it is plated. (Brake lines are not ally) Usually tin plated but some are cad or nickel. If you have a spare line laying around cut it or sand it heavily and watch it rust.

After years of exposure my 71's lines needed to be replaced. A double flare tool, 25 ft spool of 3/16" brake line and new fittings got that new shiny look post haste:)

Using a paste polish while more laborious would remove the least amount of plating. It's easier to replace IMHO.
