This is a bit OT but may be helpful. My FR-S does not have much plastic trim but my Ford Escape has a bunch. I have tried various plastic trim restorer products but none have worked well or lasted. This guy does a good review of them and found Cerakote Ceramic Trim Coat the best.
TW says you can use its Hybrid Solutions Pro Graphene Flex Wax on plastic trim so I gave it a shot, since I already have it. Sprayed some on a small microfiber towel, applied it directly to the plastic trim on my Escape, and buffed off the excess. It looks good, but let's see how long it lasts.
