What is it in Nufinish that make it work?

Wash-ar15 · 12-21-2009, 18:27

and can the results be duplicated with something else? My 223 been sitting in the new corn cob i got today for 5 hours. A little dissapointed in that its not as shiny as I thought it would be.

I was adding nu finish to my previous media with good results. Unfortunate I am out right now. Being a car guy also,I have rubbing compound and assorted polishes available.

Would these work as good as nu finish?

Rubbing Compound works. Paint thinner is as important if not more so in my experiance.

NuFinish has a trace of ammonia. Ammonia works well and is in most brass polishers.

You might want to double check your info. Ammonia is not good to polish with and products with ammonia should not be used to polish your reloading brass. Ammonia weakens the brass and will cause it to fail / crack sooner. With that Nufinish does not contain ammonia

According to the MSDS sheet for Nu Finish it does not contain ammonia.

what does the paint thinner do??

oldsoldier · 12-22-2009, 15:23

I don't know about paint thinner but I do know a 50/50 mix of Nu-Finish and mineral spirits works great! The mineral spirits will help cut the powder residue inside the case. If you do try mineral spirits make sure to get the low odor stuff. You can experiment with the mix if you want. Some folks swear by a 75/25 Nu-Finish/mineral spirits.

PCJim · 12-22-2009, 15:57

Paint thinner / mineral spirits is basically the same product. They work because they are petroleum based cleaning agents.

I use 2-3 tablespoons in my media (run for 10 minutes before adding brass!) and have been using the same walnut for probably well over 10K cases. Haven't yet changed the media, although it doesn't cost much to do so when you purchase it at Walmart.

Colorado4Wheel · 12-22-2009, 16:07

I don't know but paint thinner really makes a difference. One time I put too much in and they came out real shinny. Media almost turned clumpy for about a hour but then it evaporated and was normal. I most have put a 1/4 cup in that time by mistake. In the end, outside of cases very clean looking, inside the same as always but no clumping either.

The paint thiner knocks down the dust more than anything. I run walnut hulls and NuFinish and the cases look like a diamond in a billy goats butt!!

That will certainly attract the ladies.

So it only takes 2-3 tablespoons of Nufinish to polish. Do you need to add it to every batch or will it last for a couple of batches. I have been using the dryer sheets and man do they suck up the dirt, they are black when done so they are working.

I only add 1/2 cap full to every batch. That seems like plenty to me.

Myke_Hart · 12-26-2009, 16:28

Nu-finish is made from the dust of ground fairy bones.

The stuff is magical.

A cap full in every load, does the trick every time.

ronterry · 12-26-2009, 18:52

A lot of car polishes (NOT WAXES) work to the same level, however nu-finish is probably on the higher end of the abrasive scale. That and I agree on the fairy bone dust, and a pinch of love from the lady in the lake.

+1

Nu Finish is basically made of a solvent and two abrasives but no ammonia.

There is a trace. Below a certain percentage isn't reportable on the MSDS.

Nowhere on the package nor the MSDS is there a claim of any trace of ammonia yet you insist that NH3 is to be found in Nu Finish. Where do you get your information from?

I don't think so.....

Nu Finish is sold on amazon.com. In the listing for the product, it says:
"unlike household dishwasher or laundry detergents, it contains no alkalis or ammonia"

http://www.amazon.com/Nu-Finish-Care.../dp/B000AS495Y

In fact, if you do a Google search of "nu finish ammonia", you'll get plenty of hits that specifically say "no ammonia".

RustyFN · 01-07-2010, 18:53

I just wanted to follow up with everybody. I e-mailed Nu Finish to ask about amonia and this was their responce.
