Hello,
This is a quick tutorial on a few tricks I like to use to achieve cool looking weathering effects with pastel chalks.
A lot of times pastels are used dry to be brushed on, but this is the wet method.
This is what you’ll need.
Orange pastel chalk
Burnt sienna pastel chalk
Cup
60 grit sandpaper
Long bristled pointed brush
91% alcohol
Rub equal amounts of the sienna and orange colored chalk onto the sandpaper, then shake the powder into the cup.
Add roughly a cap full of the alcohol, then mix.
Dip your brush into the solution. Allow it to soak into the bristles, use a lot for more weathering, or just a little for dabs here and there.
Carefully dab the tip of the brush where you want the color to go, it will run into all the cracks and crevices quickly.
After the alcohol evaporates, it will leave behind the gritty residue of the chalk, creating a very realistic example of real rust.
You can use the same with black to reproduce oil and hydraulic leaks.
And this is the result.
