Paint or no paint on brake booster and master cylinder for my 71

[ottawamerc]

Hi Guys

I'm converting my 71 from manual brakes to power but I'm not sure if the brake booster and the master cylinder where painted or left natural?

Any suggestions?

Don't these parts normally rust if left untreated?  I would paint them to keep the engine bay looking good...

+1 on painting the master cylinder a 'cast' color or at least wiping it down with wd-40 regularly... just installed a new master cylinder, and the next time I opened the hood (less than two weeks later) it has a nice even brown coloring to it

And for the rest of us that didn't paint it, I'm assuming we can 'prep and paint the master cylinder anyway?
