Weathering Wash: Spray on or Brush on?

I use a weathering wash on most of my buildings, particularly yard buildings and storage sheds etc. I have always used a 1 inch camel hair brush to apply it with. Now I have an Airbrush. How does an airbrush work for applying a wash?

What do you use and why? Anyone have any special techniques they use?

I use a 1/2" brush for my washes. It allows me to flow it down a building just as the rain would do in real life. An airbrush can still be used for an overall toning down of the finish. Both work but it is best to try it out for yourself and see what you like best. Don’t be afraid to try anything.

good luck,

Bob

It depends on what you are trying to do, for instance

If you want the wash to settle on low spots, crevices, etc brush is the way to go. I use this with a dark wash on radiators, grills and similar items. Lay the item flat and the dark settles in the low spots, the solvent evaporates giving the grill some appearence of depth.

If you want someting to look rusty or dusty, spraying a wash will give you more control on how much goes where. The solvent evaporates quickley without running (hopefullly) leaving a dusty patina.

For some examples:

I used a light spray of boxcar red to fade the lettering on this car

On this GP7, I used a black wash on the grills and spray of grimey black and roof brown fo rthe grime and rust

ON this boxcar, I use a light spray of roof brown for rust on most of the body, but masked off there the Penn Central noodle logo appeared to simulate a paint-out when Conrail took over

I had a photo of MEC 263 that showed is with a lot of mud grime and sprayed a Floquil grime wash to make it look like the photo. I also brushed a black wash on the grills and let it evaporate for depth
