Monty Python Posted October 23, 2014 Share Posted October 23, 2014 (edited) Have been looking at various sites for a decent match for red oxide primer as used on German WWII vehicles. As far as I can see, Humbrol Hu70 looks to be a useable match. Has anybody else got any ideas on this. TIA Chris Edited October 23, 2014 by Monty Python Link to comment Share on other sites More sharing options...
JackG Posted October 24, 2014 Share Posted October 24, 2014 Hu70 appears to be the same match as listed here: http://www.miniatures.de/colour-ral-farben.html#footnote regards, Jack Link to comment Share on other sites More sharing options...
Black Knight Posted October 24, 2014 Share Posted October 24, 2014 I dont know just what shade you are after but my Humbrol 70 is quite a pink, nothing like the darkish brick red its supposed to be like. For use on bricks I add some Humbrol 10 dark brown. Link to comment Share on other sites More sharing options...
Graham Boak Posted October 24, 2014 Share Posted October 24, 2014 Red Oxide primer is available in model railway paints. Unless the WW2 German one was significantly different? Link to comment Share on other sites More sharing options...
JackG Posted October 24, 2014 Share Posted October 24, 2014 I've found this photo (linked from a missing-lynx discussion) which is suppose to be original primer from war time. The area was purposely exposed when some zimmerit was scraped off this vehicle at the Fort Knox museum in the US. - Take into consideration monitor settings, but also the fact that during WW2, the German industry was using natural pigments in their paints, opposed to the synthetics of today. What that means is back then the colour batches could vary, so tracking down an exact shade of oxide primer isn't necessary unless you have an actual paint chip from the real vehicle to compare with. Indeed as Graham mentions, the red primer found in model railroad paint lines is quite popular for this, while others may chose another brand or even mix their own. So it it seems it is a more personal choice since very few, if any, reveal what their decision is based on? I know LifeColor (UA231) have bottled a primer specifically for this, but the swatch provided on the internet looks to have a hue of earthen brown: regards, Jack Link to comment Share on other sites More sharing options...
Monty Python Posted October 25, 2014 Author Share Posted October 25, 2014 Thanks for the replies, some useful help there regarding different brands. I have an old tin of Humbrol Hu70 which looks as though it's good enough for me. It turns out that what will be sprayed that colour will hardly be noticeable. I have a set of Tank Workshop radiators for the Tamiya Tiger 1 Mid version and after placing them under the grills, you'll probably need a magnifying glass to see them properly.

bobmig Posted October 28, 2014 Share Posted October 28, 2014 Everyone is right! (How often does that happen!) Unlike colour topcoats, primers - e.g. red lead, red oxide, zinc chromate - are formulated to a specific chemical composition, rather than for a specific hue. The appearances can vary widely depending upon manufacturer, production lot, application, etc. The primers were not intended to be seen so the actual colour was not that important. Some primer coatings are colourless. Adding pigment helps in the application, as the painters can better see what they've coated. As I understand it, red oxide primer is a reformulation of the old red lead, as lead can no longer be used in paints. During the war it surely would have been red lead primer, the same as used on ship hulls. Link to comment Share on other sites More sharing options...
AgentG Posted November 1, 2014 Share Posted November 1, 2014 I like Vallejo 982 "Cavalry Brown". It's just red enough to look right on wheels and such. G Link to comment Share on other sites More sharing options...
Nick Millman Posted December 3, 2014 Share Posted December 3, 2014 Red (iron) oxide exists in many forms and in both synthetic and natural versions as Pigment Red 101 and 102 (anhydrous iron(III)-oxide/ferric oxide) respectively. It is not the same as red lead chromate which is Pigment Red 103 or as red lead (lead tetroxide) which is Pigment Red 105. All forms existed in WWII. Humbrol 100 Matt Red Brown is a good "generic" for newly applied red oxide. Link to comment Share on other sites More sharing options...
Canuck63 Posted December 29, 2014 Share Posted December 29, 2014 Chris,I've been collecting WW2 German Militaria,Uniforms,equipment and parts of vehicles for the best part of three decades and I can assure you that in my collection of vehicles parts (now long sold!) there were at least 10 different shades of "kommis" (the German for GI,WD anbd so on)ROP,which is absolutely identical to the ORIGINAL Regio Esercito ROP (I still own a tin of it!) and a perfect match for the ROP used by the Russians and spot-on when compared to what the American used and,guess what....you can have the same just by checking at any shop storing automotive primers...IT'S JUST MINIUM/RED LEAD!Don't be too @n@l/obsessed,matey!Here you go a picture of a WIP of mine primed with ROP I've bought at my local paint shop which is identical to a specimen I had...they made a spray can for me when they told me that they had the very same shade made by an Italian manufacturer!Along with it I'm posting pictures of other WIPS primed with ROP I've found in other shops...tell me which is which!Keep in mind that each and every one is a perfect match to some original item I own,in fact I'll use it as to prime the WIP I'll be working on at that moment!CheersManu Take a look here as well:http://www.militarymodelling.com/forums/postings.asp?th=76830http://www.militarymodelling.com/forums/postings.asp?th=76830http://www.militarymodelling.com/forums/postings.asp?th=81641 Link to comment Share on other sites More sharing options...
cossack52 Posted January 6, 2015 Share Posted January 6, 2015 for some time i've been experimenting with primers as a way of pre weathering the top coat.i've found a large can of autotek or hycote red primer is excellent;doesn't look too far off,covers in one coat.at about £5 for a 400ml can,it will prime a hell of a lot of kits!even the mean machine ptimers,£1 a can at the local pound shop gives quite good results.i use the red on lighter schemes,and the black on darker schemes.with a little airbrush practice,some interesting finishes can be acheived 1 Link to comment Share on other sites More sharing options...
