I am looking for paint recommendations (prefer Humbrol) for Parkerized steel. I am trying to whittle down the list of Humbrol greys and am thinking Hu87 might be the go but have never seen it except on a colour chart. Grateful for any suggestions ...

Cheers,
Dave

I had to look up Parkerizing :airhead: which would appear to be the process of phosphating. As it happens, one of my first jobs was metal finishing/plating and we used to phosphate car parts. From memory (about 40 years ago) it was quite a dark grey, but images I found in my search were more like gunmetal (53 or 27004) :juggle:
What is it for :?:

From my experience in various car pre-treatment plants, the phosphorous coating varied from dark grey to a greenish grey. But they were always some shade of grey.

So I think you would have to know about the treatment process of the manufacturer of what ever it is you are painting in order to be completely accurate.

I recently learnt that the MGs carried by US tanks were Parkerized during WW2. To quote from Modelling the US Army M4 (75mm) Sherman Medium Tank by S. Zaloga:
Quote:
Another colour note worth mentioning is the finish on wartime US machine guns such as the ubiquitous .50-cal. These had a Parkerized finish, which was a dull medium grey, sometimes wandering slightly towards a greenish shade. Modellers tend to prefer a dark metallic finish, but in fact the weapons had a dull finish better replicated using a medium grey colour.

So my candidate list at the moment is Hu87, Hu92, Hu106, Hu145 or maybe even Slate Grey (given the "greenish" comment)...

FWIW, my only experience with a parkerised finish is the .303 Lee Enfields I own plus militaria seen at shows. Its never dead flat in appearance, especially when it's been oiled & handled so something with a slight satin finish would look better than a matt to my mind. Maybe a satin dark gray with a tiny bit of #11 in it.

Hmmm,

This seems rather more complicated than I first thought. A little more research suggests variations during WW2 due to changes in the process, as well as after the war. Part of the problem is lack of contemporary colour references and the problem with museum examples is that even if they have been Parkerized it has most likely been done using more modern methods which I understand uses different metals.

I concur with adding some metallic element to another colour rather than using a plain matt but think I will still need to experiment.

I have turned up quite a but more info since first posting. In case anybody else is interested here are a couple of the more useful links I found:

A dark gray should do it at scale.
The real color differed depending on the metal being colored and the aging. I have an M1 Garand and it is medium gray with silver edges where the finish has worn off after 50+ years.
