    The turbine system works well for an all around system for priming and painting aircraft parts without a big air compressor. It works well with most fabric systems as well and you can get fresh air for a breathing system when using polyurethane pants as well. Compressed air systems do tend to atomizer paint better and is what Stewarts recommend with their system. Does cost more though.

    Jim,
    With a small compressor 2.5 HP from these people, an air filter/regulator, and http://www.harborfreight.com/air-too...gun-66871.html you can paint a lot of your parts. At $14 you can have one for primer and one for color.
    A source of compressed air will allow you to use one of these, http://www.harborfreight.com/1-4-qua...der-52848.html and more.
    You may still want one of the turbine paint guns, but I expect it will be some time before you do.

    I used a turbine and HVLP gun to shoot the EKOPOLY on my Vagabond wing. It did fine.

    Did you take any precautions for cooling?

    Yes, two lengths of hose. The gun handle never got warmer than my hand made it.

    Same setup I painted my Clipper with except the last pass on the fuselage. Got tired and weak and let a pro do it.

    That is what I was considering, I think cost wise I'm about even on buying a turbine or the compressor and gun. Good to know.

    Thanks.

    I spayed my fuselage and wings last weekend with Stewart Ekopoly. What can I say..... itīs very tricky. Thereīs only a very tight room to decide for orange skin (too less paint) or runs (too much paint). Three sides of the wings (two top and one low sides) have runs. The 4th has orange skin.
    What is your experience ? I sent Stewart an email which the question of what can I do, but no response. I think they know of the problems.

    Based on my limited Stewarts experience, that looks like you had the gun too far from the surface. I can't be sure but that is what I got at first.

    Did you do the old multi coat method or the fog coat / wet coat method?

    I also used fog/wet coat. I played with the paint volume a bit because it seemed to take a long time to fog the color. My first couple small parts had some thin spots.

    What gun are you using? I used the Tekna Pro Lite. I used about 1/2 a turn for the fog coats, 3/4 for the wet coat. The distances that Jason quotes in the video are what I used, especially on the wings. I might have been too close on some of my small parts causing some runs. Yes, I had nine small pieces to paint and I have some with thin spots and some with runs.

    What was your viscosity? I had mine all mixed in the 23-24 second range except the first batch, that was right at 21.99999 seconds! Dan wasn't kidding that a little water goes a long way!

    The first two pics are the finished wings, I'm happy with them considering I'm a first time painter. The third and fourth pictures are runs, one on the right wing in front of the tank bay and the other on one of the ailerons.
