So I recently went into my local paint shop to get some touch up paint for my E and while I was waiting for them to mix it I was looking at their car care products. I found this spray wax that claimed you could use it in all surfaces including plastic s I figured I would try it. Its called System One Advanced Polishing System, Its a spray Carnauba wax and I have to say it works so well on the paint and plastic panels.. I got so tired of Armor All and all the other crap I had to use so often to keep my panels looking good. I waxed the whole car about 3 weeks ago and I have a carwash subscription plan so I wash my car everyday and my panels look as good as the day I applied the wax. It was $15 and worth every penny! https://polishandwax.com/shop/products/SYSTEM-ONE-Wax-22-oz.html There is a link and description that i found online.
