converting Revells color call outs

So Don you are a stick and rudder guy. Notice I didn;t say "old stick...".

 

I always thought exhaust manifolds don't rust.

 

Depends on what they are made of- what alloy, what process.  Some certainly do take on a rust patina.  Admittedly not many aircraft use cast iron, but some do.  Depending on the alloy, some steels do rust also.  Usually the coating is thin, more of a patina than a rust buildup.

High temperature paints are a real art, and it used to be easier to chemically treat metals than to try to develop a paint that would withstand exhaust times.  One of the most common steel treatments was to plunge a piece of hot steel into an oil bath.

Gun bluing is a good example of a chemical treatment that will still rust.  I have seen very old blued guns that will start showing some rust.  So some of these old chemical treatments should be considered rust resistant rather than rust proof.  Same thing for stainless steel alloys.  I have had really old piano wire stored in my basement show rusting.

Hello, I am converting revell callout colors to VA and Tamiya paints as thats the brands most readily avalible to me and model master but I dont use them that often. The colors I am trying to figure out are 25% steel metallic + 75% leather brown matt, Is there in the above listed that would match this revell call out. Thanks in advance, Rory.

 

From the mix ratio between steel and leather, this certainly would be the color call out for Dark Iron. You can use Tamiya XF-84 Dark Iron or Gunze Mr. Color Burnt Iron.

If this piece is an exhaust manifold, they are probably calling for a rusty patina.  If it is a manifold I paint it medium to dark gray (flat) and then dry brush a rust/medium-flat-brown patina on it.

Thanks, will give it a go,

Great chance to try your hand at mixing colors.

Model kit color callouts USED TO BE handy, but then the www came along...

Hello!

I bet Revell just meant "Make this part here look nice, rusty!" - so I don't see no point in sticking to an exact paint colour here, think "rust!". Mixing some metallic colour with some brown might still be a good idea here. Colour conversion charts aren't that accurate neither, anyway. Good luck with your build and have a nice day
