When I get my filthy mits on a BCM upper this year I’m planning on shaving the FSB and coating. I’m just not exactly sure which Aluma-Hyde coating is the best match.
I’m guessing Dark Parkerizing Gray?

Hot Pink
Well that’s a thought…![]()
Black for a BCM. Tape it off and who gives a shit? I assume it’ll be under a rail or you wouldn’t be cutting it right?
P.S. Buy the extra nozzles for that crap. One nozzle lasts for one job pretty much.
Thanks Mark, that’s the plan.
I just did one today with Rustoleum “High Heat”
Label says…
Resists heat up to 2000F
Gas and oil resistant
The color is perfect IMO. (flat black) not a deep black
We’ll see how it does.
Be a lot simpler to hit with some cold blue
I used Rustoleum High Temp Grill Paint also.
It has held up good and matches the Parkerizing about perfectly.
That’s what I did with the two I have cut down and they look fine.
Yeah, I was pleasantly surprised with the color.
Not sure if I believe the whopping 2000F claim though…I’ll see how it does.
These two pics are Aluma-Hyde dark parkerizing grey on a BCM front sight post/gas block. I knew it wouldn’t be an exact match but it’s under my rail so I really don’t care. Black was out of stock when I needed it.
