Mike:

Unless you live in a very corrosive enviroment, say coastal closer to the 
equator I would not worry to much. At least you can see the exposed bolts 
during scheduled maintenance times. The bolts unless coated with paint or 
galvanizing will rust. It will take quite some time before the rust will cause 
any significant damage. It will quite obvious before that point visually.

If you are on the coasts, left,right and gulf, then I would be more vigilant. 
If on the great lakes I would be vigilant but not as much as salt water.

Accept the patina, unless it stains too much.
