Mine is rather dull and I'm curious as to whether it is plastic or metal and what sort of products can be used to get the shine back into. Searched and everyone seems to have advice on how to black it out but nothing really on how to make it shine...

 

eagle one never dull. back when I had an 87 buick regal this stuff was amazing on those giant bumpers. really shiny! very clean looking. good luck with it
