I painted those side mirror base with primer and black automotive paint. It's been about 8 months now and no peeling. Glossy shiny!

 

Update. Mirrors have been holding up decent with the Back to Black. Hasn't rained too much but in general I'm starting to be impressed. I've washed the car a few times also so it's fairly washing resistent.

 

i got a product called TM 1000 from my local detail supply guy and the stuff is great. no mess putting it on and last quite awhile, even through rain and i live in Seattle area lol. it comes out kinda like a lotion so you just put it on a rag and apply. I dunno if its available to everyone but the Co. that manufactures it is called Transportation Maintenance Products. its non silicone so ur not just hiding until water hits it

 

I'm also in Seattle. But for reference, B2B also looks like a lotion.

 

I'm using B2B and am pretty happy with it. After I did it a few times the look has become pretty permanent.
