Power brake question

[northcountry67]

I spent 10 years as a mechanic in the Army and the old 2 1/2 ton truck had the master cylinder under the floor and it was the most miserable thing on earth to work on. Does the underhood really need to be that clean? A nicely painted booster and cylinder can look pretty nice. Thanks for the input, but I think I'll stick with something easier to get to if needed.
