sorry i'm SO late updating on this, but here's my review of my Ridgeway Blue cerakoted light thanks to benthiccracker (every time I read your username as "ben the cracker" haha):
I recently got my 18mm bored 6P (with a Z44 bezel, Z41 switch) cerakoted through benthiccracker and it is phenomenal!!!! The blue is absolutely the perfect shade (not too light, not too dark). The 'feel'/grip to it is perfect. It's not coarse, it's not smooth, but the perfect intermediate. It also feels incredibly durable (to my hands at least) and the ridgeway blue goes excellently with a sandblasted crenelated bezel.
I'll give benthiccracker a 10/10 for the extremely consistent communication throughout the whole process and, of course, his guy who does the cerakote, a 10/10 as well. benthiccracker said his 'koter was a perfectionist and I can't argue with that statement given the results I have now seen.
if you haven't ever gotten anything cerakoted, do it! The price is right and benthiccracker is enabling this process to be affordable to us all.
I know I've seen pics of HDS Systems lights with cerakote that has rubbed off, but I don't believe that'll be an issue with the way this guy did the 'kotes.
The feeling isn't exclusive to me, either. Everyone I've shown my newly cerakoted 6P to thinks it is quite the good looking light and they're always amazed.
(feel free to put the above review in the first post/OP so we can get this second run some good momentum)
