I never thought of using Solutions Finish on powder coated metal. I always thought SF was only for plastics. Good to know!
I learned it by accident. Trying to apply SF to the windshield cowl. It can be next to impossible not getting any on the wiper arms on some cars. When I wiped it off I thought that it looked pretty good with a nice matte to satin finish on the powder coat. So I did the entire wiper arm. I think it looks better than my attempts to use a polish or paint cleanser on the powder coat.
