Rust question
I converted the brake system in my 1960 to disc with a dual master several months ago. While sitting it has already developed rust on the master and calipers. I can get the rust off, but what is the best way to prevent future formation and keep the original look? I know Por 15 comes in clear? Recommendations? Thanks.

Rust is always a challenge!
wire brush
air gun blow
solvent clean
prime with rust converter or any quality primer
brush on paint (POR 15 w/top coat) or any quality paint such as Rustoleum 7777.
Now how to prevent further rust in the future? a garage is 10000 times better than no garage; but, it doesn't prevent rust from occurring. Even with a heated garage you can and will get rust which is a function of humidity because the heat is not always running. Rusting will occur when relative humidity levels go beyond 50 which can occur almost immediately on a humid day or during a rain day and can quickly reach levels of 60 -80 or more. I found this out the hard way when I cleaned my sway bars via grit blast then had them heat treated to obtain the original natural heat treated color, and in less than a month they had 100% surface rust !!!
Long story short; I got a small digital temperature/humidity gauge at Home Depot and was amazed with the humidity levels in my garage on a rainy day ----------- so I purchased de-humidifier and set it to 35. It's now been 3 years since I repeated the clean/heat treat process on my sway bars and they look like the day I did them (ZERO RUST)!
The 66 has a number of parts that are required by NCRS to be "natural" and those parts especially are prone to rust very quickly which I no longer worry about.
I'm utilizing a professional grade de-humidifier; however, the ones you get at Home Depot or Lowes work just as well and are relatively inexpensive, I also recommend a digital humidity gauge as well.
Hope this is at least fuel for thought whereas you asked: how to prevent future formation of rust? --- the answer is: ----- you really can't 100% unless you control humidity which is problematic for these old cars !!
