How to hide scratches in galvanized metal?

My name is Michele and I work for a sheet metal company. We have made some bulletin boards out of galvanized metal, however I am not happy with the finished product due to the scratches, is there any kind of product you can use to give it a more aged appearance kind of like patina for copper?

I am also looking for a patina finish on galvanized sheet metal. I have a client who wants a greenish/aged look. Any suggestions?

Hi Michelle.
Its not clear if the scratches are already present in the purchased galv before you process it.
In this case just blame the supplier!
One company has developed a Cr-free passivation process for continuous galvanized strip, that gives a significant increase in scratch-resistance due to much better lubricative properties of the product.
Anyway: talk to the suppliers!
