I had stacked the roofing for a few months before I waas ready to use it and moisture had stained many of the sheets. Is there a solution that I can use to remove the stain? Thanks! Brian	Guest User 2/9/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12740/find/
You can try going over it with steel wool but it looks like it started rusting; there's nothing that's going to cure that other than coating it.	Guest User 2/10/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12741/find/
This looks like zinc oxide and actually rust in some areas. The zinc oxide is mainly an aesthetic thing at this point ... but the rust is a concern that would require coating it.
