What is the best thing to spray on brake lines, tranny lines etc., that have surface rust on them? Is there any type of oil or coating used for this purpose?
The cheapest, cleanest and easiest way out is to sand the surface rust off as best as possible and get some brush on paint. The hard way out is to change the lines to stainless.
Aren't the coolant tubes and the entire exhaust stainless steel? Don't they show surface rust? Some steels are classified as "weathering" and will form a layer of rust on the surface that actually PROTECTS the core from further oxidation. Not sure if that is what the brake lines are doing but it is something to look into.

Brake and tranny lines are not stainless.
There are rust converting sprays, which will help, but surface rust is not bad... when you have flaking brake lines, then those need to be taken care of
The thing about the rust converting sprays is that you have to get all of the surface completely penetrated. If you don't, the spray can become a trap holding in moisture that gets through the parts the spray missed. I think the best solution is to convert to SS lines. I used the Fiero Store lines and have been very pleased with them. Brake lines are a place not to scrimp.
Talking to a guy that has a Mercedes Benz repair shop told me LPS 3 is the best. Best is to spray it on every so many weeks. Every fresh coat attracts dust which in turn holds more LPS 3. Once you get several layers on it provides a very moisture resistant coating.

I have, I like it. With any of these results depend on how rusty it is to begin with. I was looking for something I could spray on before winter on my daily drivers which see alot of road salt. It "neutralizes" the rust that it touches and leaves a coating that blocks the water and salt. Its very hard to measure how much it "neutralizes". I mean I only have a visual and non failure of something like a brake line for example. But it seems to work well. I reapply some each fall in areas that look like they could use another shot.
Its an alternative to blasting the part or wire wheeling it, rust converting priming and painting with expensive sealing paint. Which in the road salt never seems to last very long anyway. Or replacing parts. I did the entire floor pan and many frame parts of my Sonoma, also popped out the drain plugs in the rockers and sprayed it in there and then put the plugs back on. I reached up and sprayed it on on teh backside of the rear wheel wells behind the outer bed-side, took out the tail lights and blasted it in there onto the wheel well and bedsides too. The truck had rust in areas when i got it, I'm just trying to slow it down.
2.5 it sounds like it will work for what I want. I just bought an 04 Chevy Venture van from Ormond Beach Fl. and some of the undercarriage is rusty, probably from driving on the beach. Thanks for the info
