psilvers Posted January 2, 2012 Report Share Posted January 2, 2012 I am coating some jigs with powder paint for the base coat and the airbrushing other features (e.g. a dark back ). That is the jigs have the basic colors of a baitfish - light belly and a dark back. I am using an Iwata Eclipse and spraying Golden Fluid Acrylic that is diluted with their airbrush medium 1:1. When I spray with airbrush the back will get dark (with a lot of paint) but there can be white spots that will appear (i.e. the white powder coat base). My thoughts are: 1- decrease the pressure on the compressor ~ 40 psi 2-Dilute the paint less Is that the problem, or is there something else going on here? Thanks for the help.

Pete The first thing to try Pete is the paint feed, there should be some sort of way to control how much paint versus air going into the brush. The next thing would be the air pressure, I had a single action air brush and I wasn't good with it but if I had a stencil I could make it work. Look to see if there is a way to regulater the paint/air mixture, you may just need more paint at a lower pressure. Quote Link to comment Share on other sites More sharing options...
psilvers Posted January 2, 2012 Author Report Share Posted January 2, 2012 Thanks Smalljaw! I can regulate the paint/air mixture using the trigger - it is a double action airbrush. I will also try decreasing the pressure. Pete Quote Link to comment Share on other sites More sharing options...
Basseducer Posted January 2, 2012 Report Share Posted January 2, 2012 Pete, Powder paint is very slick and most water based paints have a hard time adhering to it. You may have to give it a light coat and then come back with a second or third. You may also have some contaminants on the jig that would cause the paint to separate like D2T on a crankbait. You can also achieve the desired effect with all powder paint. Quote Link to comment Share on other sites More sharing options...
psilvers Posted January 2, 2012 Author Report Share Posted January 2, 2012 Basseducer - good point. I need to wipe the jigs down with rubbing alcohol before I spray them. I can also try the light 2 coat method. I have also done it with powder paint/powder water but that is a bit more of a pain to use.

Basseducer Posted January 2, 2012 Report Share Posted January 2, 2012 Pete, I spray the powder so after the white or pearl base coat I just heat it a little and spray the back. Or you can tap the second color on like Cadman. That way all you have to do is cure. Quote Link to comment Share on other sites More sharing options...
psilvers Posted January 2, 2012 Author Report Share Posted January 2, 2012 I have tried spraying the powder with the Badger Sandblaster. It is a bit difficult because the jig has to be heated and certain areas need to be masked, otherwise I get effects I don't want. Part of that has to do with the shape of the jig - there is a belly to the jig, so spraying the back will also hit areas further down. I may just go back to the powder water/powder paint. I just wipe off any overspray on the jig. That is actually one of the things that I liked about the acrylic paint, I could wipe off any overspray. I found that other psints would tend to bleed into the base. Pete Quote Link to comment Share on other sites More sharing options...
