Keyda, you probably know this, but Museum operations are always way under funded.
I can't speak for this one, but for one I'm affiliated with, all of the volunteer enthusiasm can't ever make up for hard facts of financial life.
If your ship was 5-O Ocean Gray in the war, and the Navy gives you a stock of 5-H Haze Gray, chances are are the ship is gonna get painted Haze Gray all day.
And if it's only enough to cover the parts that are the worse for wear, that's what you do.
