I am really interested in what other people are using on their black trim too. I just posted in another thread, asking the same question. On older cars, I actually used a black plastic spray paint (for vinyl chairs and plastics) on the bumpers/trim to make them look like new again but I'd never do that on my 2016 CX-5. The "Armor All" type spray I use doesn't last but a few days where I live. I was thinking of using a thick tire gel but didn't know if that would be harmful to the plastic. If nobody knows of anything that lasts for months, I'll try the "Mother's Back to Black" that rsvinylgraphics mentioned. Thanks.
