Thinning Tamiya acrylics

You can use regular old alcohol, but it might leave a gritty finish due to the alcohol drying up the paint in mid spray. You can get a pretty big bottle of Tamiya thinner for 7 or 8 bucks (not including s&h) from most any online retailer if your local shop doesn’t have it. Bottles lasts me 10-20 models.

Or ..... because most Tamiya paints are airbrush ready, you don't have to thin them at all.

water works ok. Some use distilled water because there water has alot of impurities that leave a residue. I use tap water with pretty good success.

I sve the thinner for cutting it or for stuff that is hardenend or difficult to clean out of the brushes. Usually during airbrushing, I'll run some thinner between colors just to flush it or alcohol if I'm short.

i use plain old water with no problems!!!!

I tried shooting it straight out of my Paasche VL, but it had a hard time suctioning up!!

I use Alchohol....for thinning/spraying....for brush cleanup I either use water(with drop of Dawn)or Alcohol...Seems to have worked fine for me.
