Well I can't seem to log into the tech support area so this is the backup...
I'm using the black oxide kit on some hot rolled steel squre tubing pieces. They are too large for dunking and I was hoping to brush it on the piece instead. It works OK, but I'm getting a blotchy effect because the black oxide solution doesn't adhere to the steel like a paint or varnish wood - there is nothing "sticky" about the solution and it beads up and runs off. I was wondering if anyone had suggestions to solve this - I'm looking to give the steel a uniform "tint" after welding/grinding, etc. Sort of like a wood stain would do for wood.
Ideas -
lower the concentrate to water ratio. Maybe it would work better at 4:1 or 5:1 instead of 9:1? Good idea? Bad idea?
Heat up the part or the solution first.
Add a bit of dish soap to the soution to break up the surface tension? Probably mess it up but could work.
Any help or other ideas would be most welcome.
Thanks,
