OK, as stated on the weathering thread in general, we're gunna go shopping for about $20 worth of stuff. You should also consider getting some old rillin stock that you don't care if it gets ruined. You need:
3 large bottles of flat latex poster paint (one black, one white and one brown). Any cheap latex paint will do. I got mine at hobby lobby for $2 ea., $6 down, 14 to go
Get an assortment of reasonable quality small paint brushes, hobby lobby or discount store. They have 6 or 8 in apack for $3 or $4. Leaves us with the other half of that $20, eh?
At the discount store, they should have a hobby section, seperate from the toys/models, and they have artsy fartsy latex paint assortments with the littel plastic bottles stuck together with flip up caps, about $3. Look for earthy colors (see the rust section in pt 2). In the same area they should have disposable plastic pallet to mix up paint on for a buck.
Over in the moddelers area locate a bottle of Testors Dullcoat, about $3. And over by hair care, grab three spray bottles for a buck each. If you come out a dollar short, throw the pallet back; it's a luxury
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The first thing we'll do is a "dark wash". Half fill a spray bottle with water. In one of the spray bottles, add two or three tablesspoons of black paint and shake it up. Oops, put the lid on before you shake it, sorry. Then shake it up real good and then add a little squirt of dishwashing soap. This acts as a surfactant to break upo the surface tension and it makes it easier to undo the wash if we don't like it, or we get it all over mama's sink or something. In the other bottles, you can do the same thing with brown, or a mix of black/brown and maybe even try adding a little white to lighten it up for very dark cars.
If youhave nice couplers and trucks, you should remove them or cover them up. Take a piece of rollin stock oputside and spray it down real good. Completely cover all surfaces, then let it build up where it wants to and drip or run if it likes. It looks like this:
