I would like to know if anyone is using an airbrush for painting their foam planes and would like to share any information on painting. It's been hard to find anything on this topic and I would like to know if there is any prep to the foam before painting and how to mask off sections without the paint bleading under the tape. This is my project of the F-15 and would like to paint it.100_2348.jpg

Use the yellow frog tape! This stuff is by far the best.
I am looking forward to the feedback on airbrushing. I have posted many of the same questions. Instead of paying top dollar for brand name paints you might want to try using Benjamin Moore or another high quality home acrylic paint. There have been many posts demonstrating that pledge floor care is a good thinner to use. Another tip if you choose not to use brand name airbrushing paints, is to strain them with a piece of stocking on the dispensing bottle. Once you are finished your paint job it is well worth it to coat with water based polyurethane. It doesn't have much weight and creates a very durable finish. The real question that I remain uncertain about is whether or not the foam needs to be primed. I think that for darker colors this is not necessary. However it may be beneficial for lighter colors like yellow. I haven't quite work this out of myself yet. It appears that you used blue foam. I use this as well as pink from Home Depot. Most of the black writing can be cleaned up easily with alcohol. I do not have depron which is easier because it is a nice white canvas to start on. Also, you might find it easier to use a larger tip needle on your air brush 0.5 millimeter. I would be interested to see whether or not the newest line of paint from createx works well for this application. Please keep me posted regarding your progress. Pictures are great

Thanks for the advise. I have several new acrylic (waterbase) paints and a new airbrush and it spays up to 1 1/2" wide pattern. I assume you would spray one light coat and let that dry and sand, then repeat the process. I have also heard to apply the water based polyurethane at the end. You had mentioned yellow frog tape...I never heard of that. Where could I purchase that item? I really think I need to just start spraying on some scraps to see how it looks. For some reason I thought there might be someting that you spray on the foam first, to help seal the foam.100_2353.jpg 100_2354.jpg

I believe that a good sealer before you paint is Minwax Polycrylic Clear Gloss which is water based also.

i use a paasche single action siphon feed airbrush with an h-5 tip. this tip allows for good coverage at a higher volume making the job go alot quicker then the h-3. i use the folk art metallic and apple barrel acrylics. have not bothered using the more expensive model masters acrylic as the cheaper ones have worked just fine.

i have tried, by recommendation, windex or alcohol to dilute and didn't like it. it made a clumpy mess of everything. i have found that about 60/40 acrylic paint to warmed distilled water is the best to dilute the paint and not cause any clumping and gives the most consistent coverage.

+1 on the frog tape, although i have used the painters blue tape with good results.

prepping the surface with at least rubbing alcohol and a cotton swab to get all of the oils off that may have been transferred from your fingers while building is good. then if you are using tape, go ahead and scuff it with 120 grit sandpaper so the paint will stick better.

i never primed with airbrushing. did not find a need to.

only other advise i can give is paint the lightest color first to darkest color last. it may take 2-3 coats to get it nice and deep. airbrushing makes the best use of the paint without using to much compared to brushing with a brush.

here is my latest airbrushing. the first one is to show the difference with airbrush (red) and foam brush (black)

the minwax polycrylic would be a nice clear coat to get a glossy shine. i like keeping my planes low gloss because i felt that the glossy paints made it shine to much in sunlight making it had to see which color was on the top from a distance. i like flat or semi-gloss.
