I was reading on a company’s site about tumbling brass and they said that when tumbling brass it get the brass down to bare brass, that is when it will dull over time.
My question is do the manufactures coat it with something to make the shine last longer?

Never heard of a USA manufacturer coating their brass.
Re: Brass Coating
that is the only place I come across that said anything about taking it down to bare brass.
here is the quote "Q. The brass is shiny but after a week or two it starts to get darker and doesn't look as shiny.
A. When you clean with SS Media you are cleaning down to the bare brass. As the brass is exposed to the elements and air it will discolor or oxidize over-time. "
This is my first time to do any reloading but I have been reading about it for 4 years, thought maybe I missed something.

Re: Brass Coating
When wet tumbling, most people add a little Lemi-Shine to help with brass shine. Too much of it will cause discoloration of the brass. My guess is there is a tiny bit of acid in the Lemi-Shine. If you dry tumble and want really shiny brass, put 3 cap fulls of Mineral Spirits and 1 cap full of NuFinish car polish. Run it for about 15 minutes so the additives mix throughout. The NuFinish will coat the brass and keep it shiny a long time.
Re: Brass Coating
The oxidation is caused by what ever cleaning solutions used during the tumbling process. Sometimes just rinsing them off with tap water doesn't wash away the chemical compound. Like most others I use a dash of Lemi-Shine with a squirt of Dawn for about 2 hours or so depending on how dirty the brass is. I then rinse and fill with fresh water and a squirt of Armor All Wash-n-Wax and run for another 30 minutes or so. I have brass I cleaned this way over a year ago and its still shiny.
Re: Brass Coating
Thanks guys, this is once fired LC that I got about 4 years ago. When I ordered my SS pins they packed a sample of Lemi Shine so I used just a touch of that and about 3/4 Tbs of Dawn. I am using a Harbor Freight tumbler with two 3 lb cans.
I just finished my first batch of the 1K cases and all looks good so far.
I will have some question as some of the brass looks like it was very hot and discolored the neck areas on some of the .223.

Re: Brass Coating
That means the necks were annealed, which is generally a good thing.Super8mm wrote:I will have some question as some of the brass looks like it was very hot and discolored the neck areas on some of the .223.
Re: Brass Coating
Brass + oxygen = tarnish! No way around it. Wax/polish in corncob will bring the shine out and it will also place a protective coating that will help resist tarnish. Store your finished brass in an airtight container with an oxygen absorber packet for the longest life without tarnish. On the other hand, I'm pretty sure the chamber can't tell the difference!

Thanks Netpackrat, I will post up several of the concers I have with some pieces in another postNetpackrat wrote:That means the necks were annealed, which is generally a good thing.
Re: Brass Coating
that is sort of what I was thinking, when i start building a little stockpile I will vacuum pack them in lots with some of those desiccants from pill bottle and put them in cans for when the zombies wake up "LOL"cdakers wrote:Brass + oxygen = tarnish!
