I have a pole barn that has a galvanized corrugated steel roof. Last year the roof started to get some rust in a few spots. After this winter there is a lot of rust showing on the roof.
Is there any roof coating that will either slow down or stop the rusting? I don't want to replace the roof at this time and would like to try and cover it up as well as stop or slow the rusting down.
Any suggestions?
Thanks, Brian
