Brass Black

[longcruise]

I'm restocking my mostly Renegade parts onto a Pecatonica TC stock. The TG is brass and I intend to install a TC Hawken brass nosecap. To get a match up ill use a brass black solution of which there seems to be several. What I'd like to know is which one will hold up the best with use?

I've used Birchwood Casey Selenium Dioxide cold blue on brass for years w/ no problem. Same cold blue as for steel.

Is this the Perma Blue product?

Same here, BC Super Blue does the job quite well.

So, what's the difference super blue vs perma blue?

Most instant blue liquid , is Selenium Dioxide. Try to read the ingredients on the label, and they might be listed. When I first noted selenium dioxide on instant blue bottles , I asked my Father in law , ( Metallurgical research chemist ) , about it , and he said the steel company would order that specific chemical in 55 gal. drums , and use it to surface blue sheet steel , after it was rolled , to prevent surface rust . Also, this blue chemical will blacken brass .......... Hope this helps.......oldwood

So, what's the difference super blue vs perma blue?

Super blue produces a darker more black color and works better on harder steel alloys, or so it say on the bottle.

I like this……it can also be used to produce various shades of grey on steel components. Used to be offered by Kibler, but can be bought directly from the manufacturer.

I tried the perma blue on a brass butt plate to see how it looks. Not perfectly even but probably due to my hurried application.

Appreciate all of you giving me some direction.

Knock it back with some steel wool and reapply. The brass should be degreased first. It sometimes takes 2-3 applications to get to total blackout

I've had best results by using a very saturated cotton ball and lightly rubbing in long stokes till it changes color to a dark chocolate brown color, let dry , rinse with cold water , and gently rub on a coat a paste wax, then buff off.
