I'm about to overhaul the brake hydraulic system on my '80 Malibu. I have a new reproduction steel brake line kit here. Its not stainless steel, so I'm wondering what people do to try to keep corrosion from setting in on the new lines. I was thinking of polishing the lines from the master cylinder to the combination valve, then clear coating them, just for appearance in the engine bay, then just trying to use Fluid Film on the rest of the lines under the car, to try to keep them in good shape. Any other thoughts? Thanks.
