Re: blackening manganese phosphate
The link following is what I use for blackening. Park your parts first, then do your clean dunk in water, then place it in this black oxide solution for 5 minutes. Then another clean dunk and apply the displacing oil. No matter what you parts come out after parking, this solution will make a even black on all parts. Works really good.
