    How much thinner to paint would one put into an airbrush? I just got one for Christmas, but I don't know what the ratio is.

    My airbrush recommends a 50/50 mix, and I have had good success with
    it. However, I only use enamel paints. For other paints (i.e. water based)
    it may be different. I'm sure Wayne Little will chime in, here.

    No real hard fast rule on this. Depends on the paint,colour, what your painting and temperature etc. The best thing is to experiment. 50/50 Is a good ratio to start with but you will find some paint will work better with less thinner. Also, if your painting very fine lines the paint will need to be thinned more than if your painting a large area.

    Catch 22 i will agree with Bustedwing! I do know use the recomended airbrush Thinner for the actual paint you use as it allways works trouble free. I use Mostly Model masters paints from testors and I use as a starting point there ratio of 3 parts paint to 1 part thinner for Flat paints and 3 parts paint to 2 parts thinner for gloss Paints.

    Good advice from Bustedwing and Thunderthud, lots of variation in the process, only one thing to add, practice, practice, practice.

    Thanks guys. I use Tamiya and Testors, and have the thinners for both. Great advice!

    Be careful if you paint with acrilics, at long term they leave deposits in the aerograph. A good deep washing with alcohol is always helpful after painting. Enjoy!

    Depends mightily on the paint. Also depends on how you're painting. I paint in several thin passes normally, to allow preshading to show through. That requires more thinning than blasting a primer coat.

    Floquil and Alclad should be applied over heavy coats (or accumulations of thinner coats) of barrier, as they will attack the plastic underneath.

    Tamiya paints are already pretty thin, you might spray them OOB but then again you'll want to think hard about thinning a little more and going with lighter coats. Again, depends on the paint.

    Depends also on how you're applying it. More pressure might help, but don't overdo it.

    What the rest have said. Experiment with paints you like and find out what seems to work best.

    Thank you. My dad bought a massive compressor, so we'll have to see if we need and adapter for it to work on our airbrush, hopefully I can see that today.

    Make sure it has a water trap on the regulator and it would also help to have an inline water trap 12 to 20 inches from the air brush itself!
