I like to refurbish old guns as a hobby. Blue Wonder is the best of all home blue products. Is there a trick to make it stick better to case hardened metal?
It works well for a dull finish looking forba bright black and shinny i tried all of the stages and could not get it to shine
Very good Product for cleaning up your boar for your Pistols and Rifles ….. Been using Blue Wonder for several years now and couldn’t be happier. Give it a try and I promise you won’t be disappointed ……
