Re-parkerizing

[Chuckindenver]

parkerizing is a brand name,
Parko Lubrite,. the originator of phosphate coatings.
ZInc is a light grey,
Manganese is a Dark grey.
Iron is a black smooth coating.

Iron phosphate is used more for Auto and other parts,,,bolts, gears ect, really not used for weapons.
Sept 1918 Eddystone used Iron phosphate for a short time.
Winchester used a curing oil that gave the zinc coating a green hue..yellow Chromate {spelling} and all used a wax sealer after curing to keep the grease and curing oil from drying out,, however, after use ect, the wax coating is long gone.
most the greenish hue you see on issued weapons is grease, dirt, rust and grime, thats been soaked up by the phosphate coating...no real way of duplicating this, unless yoy have a time machine..

iv been using Parko lubrites manganese phosphate for about a year... it is darker, however, works just about as good as the other brands iv used over the last few years.
