Tamiya smoke

Ian, I used it to create shadows on the lower sides of an aluminium fuselage.
I thinned it down with much lacquer thinner. I recommend to not overdo things, less is more imo. And it has a glossy look. 

Can anyone show me photos of where it has been used please?

The guys have it covered,Robbo. Light coats and don't rush.🙂

This one was given multiple very thin coats of Smoke Ian, in a fading way from low to high to create subtle shadows. In fact, when you can see the smoke it's already too much, less is more.

I use it on loads of things during weathering stages, i`ve also got the Vallejo Model colour brush version.......i tend to diluite a drop of paint with some water and it makes a great acrylic non smelly pin wash or even a general wash

Robbo, just a couple views where I have used Tamiya Smoke on some heavily worn subjects; the RAAF P-40 and the Whiskey Cobra. I used a #1 tip on my Paasche airbrush and spray it at high pressure. I will dilute the Smoke with one or two drops of Tamiya Thinner in the paint cup. One pass will usually suffice for very light panel lines and maybe a few more for something heavily weathered, like the Cobra or a modern USN/USMC jet (especially one that is deployed). Smoke can also be tinted and used for fluid leaks, exhaust stains, residue around ammo bays, etc. I have tinted Smoke with Vallejo paints and it has gone on with no problems. Smoke is really very versatile and a great tool to use.
