Howdy all, after doing some research & coming to no solid conclusion, I am after some of your suggestions… About to build Tamiya’s 1/48 f4u-1a corsair. Have decided to do this in acrylics, Tamiya mainly, humbrol & if I can find someone in Melbourne (any ideas?) who stocks Gunze-Sangyo, I’d like to give them a crack. So…
Suggestions for… yellow zinc chromate…Tamiya’s suggested AS-8 (US Navy Blue)…AS-19 (US Navy intermediate blue).
It seems the more I research, the more confused I have become, so throwin’ it to you guys for perhaps some clarity.
Testors has a Zinc Chromate in the small square bottles, not the Model Master line. Not sure if it is a match for what you are looking for or not. Unfortunatly, it is not acrylic.
some more Acrylic matches for Yellow Zinc Chromate
LifeColor UA 134 Zinc Chromate Yellow
Vallejo 70923-117 Japan Uniform WW II
PolyScale 505292 Italian WW II Cam. Yellow 2
MM Acryl 4851 Yellow Zinc Chromate
these are in the order that I check company’s offering in, and I got the LifeColor first when I went looking,so, I don’t know how good the later 3 listed paints are,but, the LifeColor looks great to me
Going for the tamiya xf-4 in acrylic. Also found that my local hobby shop does Mr Hobby acrylics ( I didn’t know it was the same as gunze-sangyo), they do a green zinc chromate (after some research I found that the cockpit interior of the F4U-1 was green zinc chromate & the rest was yellow zinc chromate, not sure why though).
I can help you some with why you found green and yellow on the same aircraft
the Yellow was used as the first coat
the tinted was then put on a second coat, the only reason it was tinted was as the “second coat indicator” (there were more tints authorized than just adding black to make green)
modern ZC from the can is not done the same way as back then, so the modern method wouldn’t correlate (I think modern ZC is put on in one coat and is “better” in that only one coat is good enough)
Adding to that, black was mixed in to the chromate primer in crew areas to cut down on glare. This is why you’ll see interior green, DDG and others in the cockpit and yellow zinc chromate in gear wells and such.
Some aircraft (P-51 is a great example) tended toward green zinc chromate in the wells, too. Not exactly sure why in their case.
“Some aircraft (P-51 is a great example) tended toward green zinc chromate in the wells, too. Not exactly sure why in their case.”
It was to denote that the area had received a second coat of ZC, that was the original use of the tinted ZC,the use as a cockpit “color” came after that, other than the “happy accident” that Green ZC was good for reducing glare in the cockpits, second coats were applied in high wear areas,such as cockpits, wheel wells, inside engine cowlings, etc, etc
