Pre dip black parkerizing post dip black dye parkerizing.

Topfmine,

I don't use any pre dip, but the item will need to be cleaned to a high standard and after this I bead/sand blast it, for the dark Manganese finish I use fine wire wool as BR mentions, don't waste your money on solutions etc, two main ingredients can be bought on ebay, as for water I now collect the water from the drain on my condensing boiler.

The link below is when I first started to experiment, there is a formula near the end which I now use but still add the wire wool.

I did a few bits for a forum member some time back and one part I couldn't get a nice finish on, could not work out what was wrong until I was finishing another part, it turned out the part was resting on the bottom of the tank so was taking more heat than normal.... lots of head scratching but eventually got to the bottom of it.

All covered in the crap...so no clean finish.

Kind of Jim, it was a bayonet and the edge was touching the bottom, the rest looked ok but the blade ..... it turned out the owner didn't want the blade doing anyway and happy with just the sand blasted finish on the blade.....
