Winter Camouflage Question

[TonyD]

I would like to apply a winter camo finish to a Pz IV model simulating the "whitewash" that was used in the field. In a search I found a method where hairspray is applied over the base color (in my case Panzer Gray), then apply white acrylic paint. When dry, scrub the paint with diluted windex.

Then I came across an article where someone used a Tamiya 'Snow' weathering stick. When I went to find this product I could only find it on eBay (for $10 each!); it seems to be discontinued.

So my questions are:

Is the hairspray method the way to go (I'm sure it will take practice on some scrap plastic), or is there another technique?

Should I splurge for the weathering stick or is there another similar product available (again, I'm sure I'll need to practice)?

Thank you

Thanks Jim! Yes, I am planning to use Tamiya acrylics.

So do I use a fairly stiff brush to scrub with? Perhaps cut the bristles back to make them stiffer? 

Should I work the paint before it completely dries or does it not matter? 

Is there a preferred type or make of hairspray to use?

Sorry, just noticed that you provided a link to your video.

Still have a question on the hair spray; you say you applied the "hairspray through the airbrush"?

Beautiful model by the way, out of my league!

Thanks again, Jim. I appreciate you sharing your knowledge.
