gtechniq makes a nano ceramic coating specifically for trims, unlike cquartz which is just a hail mary covers all type product and the gtechniq can be purchased from the UK and after 8 months on our smart car, the trims themselves are still rich in darkness and bead water just as well as the paint. Otherwise we use Black Wow, but with the amount of rain in Seattle, we do see it starting to run/streak no matter what preparations were taken prior to putting it on etc.

 

It doesn't make it bigger mark...

 

RACISTS!!
