After reading through the older messages, I decided to try some of the sample 303 I got on the black plastic side mirrors of my Dodge. I wiped it on and then buffed it off.
Looked fine for a day. 2 days later: Dull! Blotchy! Can't seem to get it back to the old shiny black plastic look. The black plastic looks like it's faded unevenly. Both were nice and glossy a week ago.
Have I totally ruined my external side mirrors?
I want them to look the way they were a week ago, but clean and protected.
