My daughter bought me a Paasche airbrush for Christmas, so I've been playing around with it this past week. I decanted some Duplicolor Torch Red,[solid color, not a metallic], let it set to let the propellant "boil out", and sprayed a scrap body that I had primed with Duplicolor primer. I tried it setting the pressure at 20, then 25, then went to 30lbs, it came very dry and rough. Do I need to add thinner after decanting, if so what kind? Any tips would be greatly appreciated!

Try thinning it some with Laquer thinner. Also drop the pressure down some too and try spraying a little closer and slower. Tha paint is rough because it is drying too fast. Also primer is very porous and soaks up allot of the first coats. Try putting a few then let dry and sand with 2000 grit and higher then spray some more on. The first coats will seal the primer.

1. Generally, you'll need to thin spray-can paint a little to get it to airbrush right, so I agree with that.

2. Sounds like my old nemesis at work here: distance. Try to maintain about 8-10 inches from the object being painted and always keep your strokes paraell to the object, try not to arc your arm.

3. My compressor works at one pressure, and it seems to do well for most paints. I've never really gotten a handle on that, so I'd suggest experimenting as well and seeing what works for you and stick with it.

Have fun with your airbrush, they're a wonderful tool once you get the hang of them.

I think Charlie hit it....your too far away, I rarely thin duplacolor and shoot it at 22psi..thining it more will just make it dry quicker

What Paasche did you get ? If it's a VL-1 it's to small for overall painting. You'll need a VL-5 needle & head assembly. You can also try moving the brush a bit slower allowing the paint to build up a little more and that'll make it wetter and allow it to flow out more. The distance from the model also makes a big difference. Duplicolor that's decanted usually doesn't need to be thinned but can be. I sometimes add a little thinner just to help degas it. With out more info it's hard to tell what the problem is.

The airbrush is a Paasche H, I'm using the HC-5 aircap.

What are your tips for decanting paint from rattle cans?

Thanks

Ok now that I know what you're working with I can suggest what might help. First adjust the air cap to the point it puts out the most paint and the air pressure to 30 lbs or even more to get a decent amount of paint. Then try holding the airbrush about 6 in away from what you're painting. This should put enough paint on to keep it wet and allow it to flow out. If it doesn't look wet, you can try moving in to about 4 in. but I doubt you'll have to.
