Is it supposed to be kinda milky and thick? It's clumping in my walnut media, I had to take a spoon and mix it up as it was tumbling.

Even the media polish that you buy will clump the media when you put it in the corn cob or walnut. Let it run for about 15 - 20 minutes and it will mix correctly.

I use it in my cob media great stuff,I just shake it up first then drizzle about two caps full onto my media and let it run for about thirty minutes. It's great for shining up any old copper jacket bullets that have tarnished also makes them like brand new.

I use around 1/2 cap full. Pour it in and let it run around five minutes before I add the brass and paper towel. Works great.

Cameron,

What you're seeing is normal. Just let the tumbler run a couple of minutes and it'll mix and the clumping will go away.

Regards,

Dave

Okay, thanks everyone! I just wanted to be sure. I was sort of expecting the Nu Finish to be clear and runny, not thick and clumpy. I'm amazed at how shiny my Greek surplus .30-06 brass is! I get the cleaning power of walnut media with some great polishing power. All I need now is some paper towel strips or used dryer sheets to pick up/reduce the dust.

Amazing how well NuFinish works, eh? I've been using it for quite some time now, but recently added an ultrasonic cleaner to the mix. Polish the brass in a tumbler for a couple hours...comes out slick as snot. Then it goes into the UC to get all the dust/abrasives out of it. When I'm done, I have brass that looks brand new and won't send gunk down my nice new Shilen barrel when I pull the trigger!

It is thick and milky. Best bet is start the tumbler going, then instead of dumping a glop in there, drizzle it in slowly in thin lines like you are putting a bit of choclate syrup on a fancy dessery. Less clumps, and it will spread out quicker. The clumps will break up when the brass gets in there. You might also get a coating on the tumbler bowl, this is normal too and the brass will scrub it off.

How often do you need to add more Nu Finish to the media?

I tumble my brass twice, once to get it clean and then again after sizing to get the lube off. I only use Nu Finish in the first run. Also I put everything in right at the beginning as in media, brass, dryer sheet and car polish. I run it for at least 2 hours and the brass comes out great.

I Tumble my Ammo AFTER i reload it to remove and Case Lube and to Give a Final Polish on ammo that I care about looking good.

Tumble Live Ammo at your Own Risk..YMMV
I have been doing it for Years. <-----Which means absolutely Nothing!

I have run four batches of 200 or more cases so far through this batch of media without adding anymore polish.

I don't know if this is urban myth, but it makes sense with tumbling.

If you tumble your loaded ammo a lot (non-engineering term) and it's extruded powder, you can break down the powder from little 'sticks' to... well, 'powder.' At that point, it'd likely burn faster and create higher pressures. Maybe not a good idea.

I wouldn't want to leave my .30-06 ammo tumbling overnight.

"How often do you need to add more Nu Finish to the media? "

A LOT less often than most folks seem to think. Better to be a little short than a littlle long on polish, too much leaves a dusty residue on and in the cases.

Polish is polish, and brass is easy to shine. Use an occalsional cap full of what ever polish you have on hand an you will be fine.

Adding the soft paper stuff helps keep down the dust and it helps remove excess polish too.

Tumbler media - cob or nut - dosn't "wear out" to the point it won't work but the grains do get smaller. Actually, I prefer smaller grains, it doesn't stick in the flash holes so badly.

Overnight would be excessive, yes, but ten minutes to remove lube from the finished product should be fine.

Nu Finish is a great product, a cap full every few cycles and the brass comes out clean and ready to load.

An easier and cheaper nonclumping additive is a scrubbing powder like "Ajax" or "Comet". Simply add a tablespoon to your walnut media, tumble for one hour and you have clean and shiny brass.

After reading this thread, I tried Nufinish last night. Never seen such shiny brass out of my tumbler! Thanks to all who posted.

Question: Any idea how long the shine will endure?

50/50 mix Nu Finish and Mineral Spirits. No Clumping.

The shine will last till you shoot it. At least mine do. Then time to clean again.

Sorry I didn't clarify. What I meant to ask was how long the shine will last in storage? Reason I ask is because I tumbled some brass 5 years ago using plain walnut media (no polish) and now they have some tarnish, at best they are clean but not shiny at all.

Still conducting that experiment. At this point "A Long Time" as in over 2 years for some pistol cases that have been stored in a freezer bag waiting for a burst of ambition and a rainy weekend to coincide. rr2241tx

That seems to defeat the purpose for the polishing in the tumbler if you ultrasonic after you polish the brass. The ultrasonic will pretty much strip any coating you put on the brass and the result would be your final rounds will tarnish faster.
I do about the same process but I decap all my cases first then ultrasonic then polish. I size mine after I polish them leaving the decapping pin in to knock out any media stuck in primer holes.
On handgun rounds I don't need to lube the cases too much because the nufinish seems to give me enough wax without any problems. Rifle rounds have to be lubed.

Maybe it is just my personal preference, but I have had great results with Flitz's Media Additive. Unlike most of the polishes out there, it is made for reloaders so it is Ammonia free. Ammonia weakens brass. It can be a little hard to find, but Cabela's carries it. Nu Finishes MSDS doesn't list Ammonia, but Brasso, the other product a lot of guys use does. But as with all things reloading, their are many options and even more opinions.

I read about Nu-finish about 2 years ago. The stuff is great to really polish up the brass. I shake up the bottle a bit, then drizzle in approximately a tablespoon worth into the media, and then run it for about 5 minutes before putting in the brass. I'll refresh the media about every 4-5 loads with some more.

Adding the soft paper stuff helps keep down the dust and it helps remove excess polish too.

Try using strips of used dryer sheets. I read about this several years ago and tried it - the stuff really holds onto a lot of dirt, thereby extending the life of each batch of media. I tear the sheet up into 4 strips, which helps to circulate them to the entire tumbler bowl. The best part was the look I got from my wife of "what is this crazy guy doing NOW" when I started grabbing all of the used dryer sheets for a few weeks.

And don't forget to wrap it around you plastic powder tube. Now that realllly works. ;);););)

I was skeptical about the NuFinish trick but figured I was only out some brass and media if it didn't work. Was I ever happy with the results. It's cheaper than the "factory polishes" and it does work. +1

The used dryer sheets is a +1 also.
