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.
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!
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.
never showed up
