Im going to be doing one of my AR's in Duracoat and I need an airbrush. I have a full sized Craftsman compressor. What do I need to run an airbrush with that compressor? It has a regulator to step the pressure down but I dont know how low it needs to go or what pressure I should even spray it at.
Any suggestions? |
| You'll have to play with it a bit to find how much pressure works well for your airbrush. Mine has a tendency to make a lot of cotton candy when I'm spraying and I can't find the sweet spot to make it stop. If I turn the pressure down low enough to stop the cotton candy it spits on me. Doesn't really hurt much, the cotton candy blows of easy enough just makes a mess in the garage. I spray at around 26-28 psi. |

If you are using Duracoat and you are getting "cotton candy" try thinning the Duracoat by adding no more than 20% of Duracoat Reducer. The "cotton candy" is happening because the paint is drying too quickly based on the outside temperature. Thinning it will slow down the drying enough so you don't get "cotton candy". |

I just did my first duracoat job last month. I used a 7 gallon pancake compressor with a built in regulator. Then attached an oil/water separator, then the airbrush hose, then airbrush. I had to go with about 35 psi(not sure how accurate the guage was) and the #5 nozzle on the airbrush. I tried the #1 and #3 but it would barely spray any of the paint out of the airbrush. Once I put #5 in, it worked great. If it looks like you're getting a dusting effect on the gun, turn the air pressure down some.
For the airbrush I bought a paasche vl double action brush |
