I just cut my FSB to fit under some new rails. What would be good to coat this with? I used a Birchwood Casey pen and that just rubbed off. Is there a high enough heat paint to withstand being used to coat it?

Since it is going to be hidden under the handguard...the use of any hi-temp paint should suffice. Probably a flat black header paint would be best.

I coated mine with rust, works great.

Sounds good, thanks.

I used high heat barbeque paint.  I believe it was Rust-oleum. It's held up fine.

Ditto on BBQ grill paint. Holding up well and the color match was about spot on.

You want some sort of bluing under the paint - if just to protect it should the paint come off in some bore solvent or something.

I use G96 gun blue paste. Heat up the part a little (just warm to touch, not real hot) and rub the paste on. Let it sit, then brush off with a soft tooth brush and water. Then rub some gun oil on it with a soft toothbrush. Wipe clean, and hit it with some BBQ flat paint.

I used cold blue on mine and it matched up nicely

Just got some paint and painted it with Rust-oleum engine paint. The BBQ stuff was rated to 1200* and the engine is rated to 2000*.

Err, umm... Those are not aluminum...


I went to Autozone and bought some brake caliper paint. It's very high temp and very durable, though durable is not really necessary for that application.

Err, umm...but it works even better on steel then it does on aluminum.

Sprayed mind with 2000 degree high temp ceramic header paint like you would use on a header on a car, truck etc. You can buy it in a spray can at an automotive store for about $12~15.00 dollars. If it holds up, upto 2000 degree engine exhaust, well I've never had to respray my FSB and I've got thousands of rounds on it.

cold blue works well.

I got the one on the left-


Here it is now painted-

The marks on the barrel is tape residue.

Thanks to all that helped.

Don't forget that stuff needs baked to fully cure. A few mag dumps should do nicely!

Cold blue, then paint.  Brownell's alumahyde 2 works well.

This.  I just sanded the surface down uniformly and then blued the whole thing.  It looks nice and has held up fine.
