no problem on the sheet metal ... it did leave some small pits where there was rust when they blasted it .... so you need sameone with a good hand blasting it ... if you have moderate rust you might want to spray paint it if your looking for an automotive type base coat / clear coat finnish ... while this does shine and is easy to clean up .... it doesn't have that depth to it but does have hard long lasting industrial type finnish.

hope that helps ya
