Could I just take a jar full of thinner add a little black and then spray it onto my model. Then I would have my "wash" done, and very quickly.

Let me know, I am real close to weathering time on my model.

Chip,
I prefer to do selective washes just around raised details and into the crevices and the recesses of my models just to give depth to it. In my view, it's not easy to do it by airbrush because you cannot deposit enough paint where needed. On top of that if you do a general wash it will end up in a filter so if you use the average dilution for a wash (that's 20% paint to 80% thinner - against the filter one that is 1 to 2%) you risk to darken too much your underlying camo...
If the difference between a filter or a wash is not clear or you need more help to perform them try to have a look here.

I would honestly have to say, that you are the wash man! Thanks for the link, and I understand where your coming from.

I was just asking about the airbrush, but since it does sound like a dumb idea, I will do it w/ a brush!

Thanks again!

I don't think the idea is dumb, it just might not get you the desired affect.

And here's the 'full wash' side almost a filter and a wash in one.

I have done washes over full areas on an AFV the idea is to get a dark tone over the area and get a buildup on in the crevasses too. With a brush you have a bit more control on where the wash goes and you can easily get a build up while keeping an even layer on the rest.

I don't even have a filter for my brush. I was just going to use my cheapo Wal Mart one and use that, versus my 50 buck Aztek.

The cheap one is the one that sprays a broad area.

"Filter" refers to the effect the painthas, not a separate piece to the AB.
I would not use an AB to do a wash. What you'd be pushing through would be way too thinn under pressure and would not pool as you want it to. You'd either get everything just a little darker or wide up with nasty "spiders" frem the AB.
Take the time and do it right.
