I recently purchased several of these 4x4 bases for a rooftop very close to the ocean. They have not been installed yet.
After about a month I notice that one of them has a little rust spot where the base is welded.
Before installing them, is there anything not too expensive that I can apply so that they don't rust?
I was also thinking of covering them with something after installing them, since these bases aren't attractive. Maybe I can cover them with something attractive that would also protect them from rust?
