Question: Does it work on titanium?
Document: Don't waste your money cold blues don't work I have tried them all just live with the rust or straches or have it hot blued
followed directions and coloring did not come out like advertised. I guess trying to take a short vut doesnt work.Better off sending gun back for a professional job.
Like the title says, if you prep the gun metal properly with a good acetone clean of the area, this product will work wonders.Creates a visible chemical reaction, and you can do multiple coats to achieve a deeper colored blueing to match the rest of the metal, if need be.
This is a product I'm use to. I've used up 1 bottle and now I started on my second. The cold bluing product is one of the better one's on the market. I would say 1 of the top 3 out there. Make sure you follow the instructions as written. Good preparation also makes this product work well. For the beginner cold bluing person, this is an excellent product to work with.
As a gunsmith, I've used a number of cold blue products to touch up my personal firearms, and my customers. I've tried everything from brownells and Birchwood Casey etc. Black Magic is by far and away, the best cold blue you can buy. It works well, is super fast, nice dark blackish blue and can even take a polish if you are patient and willing to use a bit of 0000 steel wool and work on it for a while.Hands down, the best cold blue available right now.
Works niceley. Re-blues scuffs and is simple to use. Would recommend for small scratches and scuffs to cover exposed metal.
Works great!
Works great on my Mosin Nagant barrel and receiver. I would recommend this anytime over any other bluing. I tried Birchwood Casey bluing and it sucked royally. Too many streaks and discoloration. Kleen Bore is the bluing to go with on any rifle or pistol that you want to re-blue.
Worked very well, started the process as soon as it touched the metal. On some metal I wound up with a good brown rust look and others a very dark smooth finish, so would recommend trying it out on a spot that won't be noticeable first.
With no issues I installed the barrel. It still looks good, and was a simple process to apply. I recommend this product.
