I tried that Cerkote Trim kit for the faded black trim the other day. The stuff is amazing, trim looks brand new. I did not have any of the issues people have posted online, streaking, white spots, etc. I hop it lasts anywhere near as long as it says. I am going to experiment with it on anodized aluminum rails. I am pretty optimistic about it. I got a bit on by accident and it looks great. Definitely worth the effort.
