First Roon experience

[WaG35]

1/2 Gallon cheap Vinegar from Walmart($1.37) + 2 OOOO steel wool pads+ 24 Hours of soak( 12 hours in the sun)= the best black I have ever acheived. Seriously, I brewed it in a gallon milk jug then strained it back into the original bottle, then dipped a scrap piece for about 30 seconds and I was amazed at the results. I have heard people talk about blue, purple hues and even some browns. Mine is just pure flat black, and it doesn't even smell that bad. Now I just need to find a finish that will leave it flat yet add the water resistence. Man I love this place. I felt like I was back in high school Chem class. Now I must go make a holster. and try this stuff out for real. Has anyone ever had any issues with the roon affecting the finish of their guns when using this stuff on holsters? Later Kids- Tony
