restore

Hello sailors! This is my very first post on this forum, so please excuse any mistakes I make here. My wife and I own an Express 34 (S/V Wild Thing) in Seward, Alaska, which we bought back in 2021. Beautifully taken care of boat, and we really wanted to keep the high standard of maintenance...

How do I restore the shiny black color of a 5 ft long black plexiglass trim piece on sides of my Hunter 37? I used a Miramax headlight retoration polishing kit and it just got smokey.
