Back in black

I recently used the blackening kit to fully redo a 22 rifle and touch up on a shotgun. The finish turned out great on the 22 and touch up on the shotgun blended in very well.

Simply Amazing!

This kit was my 4th go to and my last. I have used 3 other blue kits on my saa colt cylinder with very poor results. The best runner up was oxpho blue, and even it is nothing in comparison. This kit is fabulous! Comes with everything you need, and leaves that desirable factory blue that everyone loves and seeks. I would not hesitate to buy another kit for all my touch up’s and full blue jobs.
My only recommendation would be to make sure that whatever you are trying to blue, is nice and warm! I found around 135° to be perfect for a nice blue with no streaking. Also, rubbing alcohol is just fine to use instead of mineral spirits. Happy bluing!

Ok. But did not get the job done.

I was looking for an alternative for touch-up bluing on a Marlin Model 99 outer magazine tube. Blue Wonder provided a weak bluing (almost blue/silver) and did not darken with repeated applications (7 applications) as advertised. Oxpho Blue Gel got the job done much better. I did not try it on a barrel (or other steel components) yet so I cannot comment.

I have not received product

never showed up

This is the best rust remover on the market for firearms!! I used it exclusively as a Professional Gunsmith

Great product

A-1 service and product

I have 1(one) more hunting season before I tackle my next rifle barrel. But I've used in the past with excellent results and it's long lasting.

Great product!

This is the best cold blue product I've used. The metal cleaner is a superb bore cleaner as well. Love it. Priced right, great shipping

Old Timer

Many years ago I bought my first tube of Blue Wonder at a Farm Bureau. Through the years I have proven it works for cleaning, removing rust but not the bluing, and trust it. I ran out so I bought one for myself, and a stocking stuffer for my son.

Very good product

I leave in France and i ordered Black and blue products to renovate a old colt.
Both products are fantastic ! Really good result !
too bad there is no distributor in France because customs fees are high.

Blue Wonder™ Gun Black Gunsmith Kit

Blacking Solution

IT’S SIMPLY GREAT. For years I’ve looked for something that can TOUCH UP PARKERIZING. And this does it. It can’t replace the parkerizing when it’s totally worn off….but when the Parkerizing is thin from light wear… it’s just the trick. Rub it on briskly… then a drop of Developer… wait an hour and SHAZAM…. that wear spot on your old M1 or 1911 is gone. WONDERFUL STUFF.


Works great when you follow the directions

Great kit and works as described

Great stuff. Are you going to be putting out a kit for parkerizing ??

Works inside and outside the barrel

removed all of my loose rust both inside the barrel and on the outer surfaces of the receiver and barrel.

Awesome gun looks like new

Cleaner/ rust removal

Love this product! Been using it for years

Got it!

I’m still waiting to try the product…have to prep the gun first. I saw a good friend use Blue Wonder and I was impressed with what I saw. That’s why I made my order. The shipping was super quick. Thanks!

Product is fine but shipping took over a month and then I had to pick up at the post office and pay the rest of the shipping. Probably won't buy from this place again

Best and Easiest Gun Blue

Blue Wonder has to be the best and easiest gun Blue to use. If you follow the directions and make sure the metal is clean and warm, you will get a fantastic finish. Deep blue luster when you're done.
Refinished my old Stevens single shot 410 and it came out great. Looks like new again. Grandson will have it to pass on to his kids.
Still have enough to do at least 3 more long guns maybe more.
Can't say enough good things about this bluing. Tried other cold blues and this one is hands down the absolute best.
Going to order the gun black next for a old pistol.

great product and the best customer service anyone could ask for.

Expired kit

I purchased two kits from you one was expired, and the other was perfect. I would like to order more, but I am unsure of getting a kit that is not expired.

Please contact us at and we will make certain we are square with you on this.

Highly satisfied so far. The directions was very clear and easy to understand resulting in a beautiful finish! Anxious to see how long it lasts in the coming years.
Thank you.

very good
