weathering lower hulls - need some advice or inspration

[Thegreenmachine]

Hello,

I'm about to finish weathering my Bismarck model and intend to weather the lower hull as well. Any advice how to do that? Is there a tutorial available or at least some good reference pictures? Bismarck didn't had a real long career but I assume the trial period in the baltic left her hull quite worn. Thanks for any help!

I would search for pictures of docked ships as an inspiration. They would indicate how wear patterns develop.
