Discolored Aluminum: Heat

Guys, in trying to finish this NMF Mig-19, the exhaust section does not have steel, titanium, etc like other aircraft. Instead that section is aluminum. According to photos, this area discolors. I’m painting this aircraft with buffing MM aluminum. How can I reproduce this effect? Thanks.

Revell do a clear Gold paint (Revell Germany, Klar 730). Try thinning a few drops of this down (very thin!) and almost ‘dry brush’ it on.

If it’s not thin enough it just looks sort of goldy/brown (my F-100 is testimony)

I tried a burnt metal technique using a couple of shades of Alcad and it came out pretty good on my first half-hearted try. It surprised me enough that I was disappointed that I didn’t take it more seriously.

Alternatively, take some aluminium foil, put it in a pan of water, then boil it up with some broken egg shells. The foil changes colour quite convincingly

Since your’e using Model Master paints you might try their "Jet Exhaust ", thinned down and lightly sprayed until you get the effect you want. It’s a brownish gold metallic that represents the heat staining pretty well.

If it’s a goldish-yellowish look you want, you could try a technique I discovered while painting a WWI rotary engine. Paint an aluminum base coat, then take a jar of MM Turn signal amber which has settled, so that all the flakes are in the bottom, dip a brush into the tinted carrier at the top, and dab it on. After it’s dry, overcoat with the proper sheen of clear, and it should look quite convincing.

Thanks guys. I think I’ll just try all of them on some scrap and see what turns out best. Thanks again!

Keep us posted Dana, I’m pretty interested to see how this comes out. That has been an effect that has always impressed me, but I’ve no idea how to achieve it.
