Painting Heat Shrouds

[Gamer_217]

Working on deciding how to paint flamers for my Salamanders and saw the heat shroud work on the Knight Warden exhaust pipes on GW's site: 

 

 

Anyone know how to get this look?

Bronze color of your choice for the base color and a very light silver for fine edge highlights. The exhaust build up can be done using a technique similar to that shown in the WHTV Muzzle Burn video. The video colors would work just as well, but it seems to me that the Knight goes from a black ink at the top (rather than purple) through shades of brown.

Very easy with an airbrush.  A bit more time consuming with a regular brush because of drying time.

 

Depending on the base metal and the type of heat scarring you're trying to achieve, you just use a series of washes: sepia, brown, blue, violet.  I'm currently using a mix of old GW washes (e.g. Asurmen Blue) and new stuff (Agrax) but those basic four colors get you all the variation you need.

 

Be patient with your gradation and don't forget to overlap the colors a bit.  If you're brushing, let it dry; it'll take a while and many coats, probably.  If you're airbrushing, don't spray too much because you'll easily cause ripples since the color is so wet; blow air from a distance to shorten your time between coats.

 

Note of caution: if you mask the exhaust at some point after you've done your discoloration, make sure you've varnished first.  Every time I've done so and not varnished, I've ruined my work.  I assume because of how little pigment is actually in the wash.

 

Here are some examples using only those four colors.  No black was used at all; personally, I don't think it gives the tone you'd want.  If you want soot at the tip, dry pigment or even black paint is a better option.  Also shows the tones you'll get with different base metal colors.  The exhaust on the Land Raider is Vallejo Metal Color White Aluminum; the muffler tip is VMC Gunmetal Grey (IIRC).  The thermal cannon baffle is, I think, Metal Color Gold, and the muzzles are Vallejo Model Air Steel.

I use silver for most of my exhausts. Then I drybrush a good chunk of it with gold, copper, or a metallic chocolate brown I have.

 

Then I drybrush the end with flat black.

Ok thanks. I'll look into testing with some gold and copper colored paints with sprue pieces to see what looks best.
