I purchased this autostopeliminator for my
2019 RST and it works flawlessly. I installed it and when I start my truck it automatically turns off Auto Stop without me doing anything it tells me on the dash that it is disabled and stays that way unless I turn it back on.
it remembers your last setting until you change it.
it can be ran with range module.

Cerakote is the way to go.
The C series can be applied with small hvlp spray gun. I Cerakote - guns/ brake calipers/
Dirt bike parts etc. it is very easy and once applied it dries to touch after about 1 hr and is at its hardest in 5 days I have found most chemicals won’t affect it. It takes sand blasting to remove.
many colors and shades of black!
hope this helps
