Look guys, I am familiar with the idea of thinning craft paint, such as those inexpensive bottles you find at Michaels and WalMart, although I have not tried them yet. And i am aware of pigment particle size differences between hobby paints and regular interior acrylic house paint.
Now, I have an inexpensive ($3.00) sample jar of a particular color in acrylic interior paint (Home Depot) that is unobtainable otherwise in hobby paint or spray paint formats. I am considering the following: thin it to a solution of 50% paint and 50% Windex (alcohol would dry too quickly), add a few drops of acrylic drying retarder (to slow the paint drying cycle)(Liquitex, the art color product line has one cheap at Michaels stores) and try to use my airbrush to spray that mix. At what pressure range is another question.
I would appreciate any feedback from others before I try this.
Sounds silly, but better to get input before I try it.

Ron,
What you are trying to do will work. Or at least it has for me in the past. I don't know about
Windex. I use something else, I can't remember the name. I think I have an old bottle somewhere. If I'm not mistaken it's the stuff you pour into your car's gas tank to prevent or get rid of water in the fuel.
As for air pressure, there are so many variables. I would start with 25 psi and work from there.
I have used Liquitex, using a retarder is a good idea.
By the way, I have several old diesel engine shells, old Athearn wide body, damaged AHM, lifelike etc. that I use a spray test dummies. I get them at train shows for buck or two.
Unspoken expectations are premeditated failures.

Ron,
guys......
I use this:
NOW, to explain. The "Red Brick" is Wal-Mart "Color-Place" Red Oxide Primer. This is THEE only "Lacquer" based "COLOR" of paint, on the whole building! The only other Lacquer paint, is at the end in the dullcoting of the entire building.
The "gray" roof is Michaels craft stores acrylic craft paint. The weathering, is done with multiple shades of darker grays and also browns.....The brick Mortar is Polly Scale (Polly S) "Aged Concrete" That's the only actual Railroad color as well!
The brown that's on the dock is NOT Tie Brown, that's a brown I got from Wal-Mart as well....I can't remember the color off the top of my head but I think its burnt Umber is the name, and I'm not even sure I ought it at Wal-Mart, that one might have came from any other place a acrylic paint rack is found!
The key to using the acrylic paint? REMEMBER to DULLCOTE the whole thing, when done! JUST REMEMBER, dullcote FIRST before you add in windows to any building!
Dullcote as we all know is Lacquer based, and is a sealant to any type paint, I have not found it to have a bad covering to any other paint type! AS LONG as the other paint types are for sure "cure" and fully dry.
Hope this helps!

NC- you're thinking of that fuel stabilizer stuff you put in the lawn mower gas tank over he winter when not being used.
John- my red color of the Siouxlake scheme IS Rustoleum red primer and my go- to gray primer us always WalMart colormate gray el cheapo primer.
I will take your advice and try ths experiment on a practice shell to see how it sprays and settles. If it works, that will be my final "novelty" car.

NC may be referring to dry gas, which is used in the winter to remove moisture from the gas tank of a vehicle. That was primarily isoproply available in different percentage strengths.
I have used iso with the acrylic straight from the bottles for washes and such, but I have not yet used them with the airbrush, so I can't help much more then that.
Blane is the name,
Trains are the game.

HEET fuel antifreeze and water remover.
But, now I'm wondering if thats what I used with acrylic paint or something else. Been a few years, ago.
John,
I don't see the point in talking about paint colors you use; when you show a picture of a real building, oh, wait... it's a model sitting on desk.

WELL, I wasn't aware that NC was asking about the fuels or Alcohols in use of acrylic paints.....I know in A LOT of water based paint.....add alittle alcohol content is a drying agent, as is Acetone to a lacquer or solvent type paint, aids in drying, specially in those place the humidity is really high.
In an air brush, only drops of alcohol would be needed for a drying agent, as to about 6 drops of Acetone, from a glass eye dropper is plenty to be a drying agent for lacquer based paints, or just about any oil based paint.
Clean up? USE Denatured Alcohol in your air brush to clean it for water based paint, any and ALL of it.....Use Mineral Spirits on any oil based paint. (I NEVER use Lacquer for "cleaning" to expensive!) And Mineral Spirits does just as good! (and is about 5 to 6 bucks cheaper to buy as needed!) I buy either or, by the gallon!
NC, Thanks for the compliment on the station! I knew it was good, I just never expected to hear that! LOL

One other concern before I experiment, as I described in my original post- what about the blue dye color in the Windex solution? Would that affect the paint color ?

Ron,
That I can't answer for. I have never tried it, the way to test that would be to take a small clear cup type object, fill with just a small amount of paint, and add I the Windex, and stir it to see if it changes the color in the cup....Easiest way to tell? use white paint, and see if the Windex gives it a blue "hue"......IF it does, and you see, you WILL see it on the model your going to paint!
I have found if the paint looks "X" this way, it will look "X" way on your model, regardless of primer color, OR plastic color for those who don't use primer....UNLESS such a light color is used for the base to "shine" through!

Ron, I've never used Windex, but I can guarantee it would affect the hue.

I don't think Sta-Bil will work in paint, I'm, not certain on that but, I know its to stabilize gasoline for storage but, paint, I'm not so sure!
