Zinc Chromate Primer Paint

Recommended Posts

Hi All

 

Haven't really been here for a lot of last year, personal and familiy

health issues have taken their toll on model building. :(

 

This new year has brought on a burst of Modelling juices and I have pulled out

of my pile, the old Revell P 40E.

 

I plan to build the P40 as one diverted to the RNZAF in early 1942, from RAF stock held in the US.

 

The Curtiss documents that arrived with the P40's are now held by the RNZAF Museum

at Wigram in Christchurch, the documents have the DuPont colours for the paint scheme, so colours are sorted.

 

One question I have, is that the Curtiss documents specify Zinc Chromate Green Primer,

in the interior (engine bay, wheel wells etc).

 

My understanding is that Zinc Chromate Green Primer, is a Translucent primer painted over

the likes of Yellow Chromate primer for two reasons: Protection, and to show that two protective

coats had been applied (think I have that right?)

 

Does anyone have a good formula for making your own Zinc Chromate (I use Humbrol)?

 

I know Zinc Chromate Green can be made by adding Black to Zinc Chromate yellow,

eg Humbrol 81 (Pale Yellow) and Humbrol 33 (Black). To me this would not give the so

called 'translucent" look, or have I got it all wrong??? Or making a mountain out of a mole

hill??

 

Thanks

You're right on target Alan. the paint formula you have laid out should work just fine, just test it on something besides your model to make sure you like it before continuing. You could also start with Tamiya Yellow Green XF-4 and go from there, that's what I've done previously.

All the best to you and your builds, and Im glad you found your way back!

The standard mix for interior green:

10 parts Green Zinc Chromate

1 part interior black

 

I tossed and turned over this when building my Mustang and all roads led to the above formula.

Keep 'em coming

Hi Gents

 

Thank you all for your replies - Very much apprciated :thumbsup:

 

Whilst hunting for some photos of my aircraft to build, I came across

these photo's (via link) on a New Zealand Forum I belong to,

- I had forgotten they were there.

 

These items were found at the old Rukuhia Grave yard (Now Hamilton Airport),

where the P40's (all marks E-N) were stored prior to meeting their fate :crying:

Note the "Apple Green" colour on this Control column

Another photo link of undercart control quite a different shade green

I will have a go at mixing my own and see how I go, if that fails, I can try the Tamiya paint

XF-4 as suggested by Paul.

 

Regards

Hi Alan

 

I use Mr Color lacquer and have found their US interior colour set has a good match for 'generic' interior green and I really like their shade of YZC. A friend of mine has several P-40 flaps (ex RNZAF dump) and they are various colours. Some are green and some are yellow!

 

Just a thought.

 

Cheers

Anthony

Hi Anthony

 

Thanks for that. I have never used Mr Color, so something to think about.

 

What's really interesting is that the info I received from the RNZAF Museum, is that

the Zinc Chromate Green was used for interior areas, but the Cockpit was ANA 611 Interior Green

(according to the Curtiss Documents), the most interesting part was that it had a bluish tinge to it.

 

In reading about the Curtiss greens made by Berry Brothers it appears that they may have

mixed it with greys in stead of Aluminium, so had a different tinge to it.

 

Regards

 

Alan
