someone recommended plexus to me. when i had scratches all over my displays. they said you can pick it up at a local bike shop.

 

Bingo. If the etching is not too deep to be removed, then a plastic polish like Plexus is the way to go. Waxing anything (including clear interior plastics) only adds protection, and will not remove imperfections unless you're using a sealant that incorporates abrasives like an AIO does.

 

I bought and used the PlastX by Maguiar as advised. Although it did not get the spots out, it really made the plastic panel looking shiny and brand new. The cleanliness almost made me forget about the spots for a while. keke I recommend you guys to try it on the plastic panel, what a shine! it only costs about 5 bucks.
