Called to inquire if their ZINC pre dip blackener would work w/ MANGANESE phosphate... Dave said that they get that question often but have never tried it even though they have fielded that question several times....
Long story short, I have a bottle of predip blackener enroute to my house FREE, just to email them back w/ my results
