So far, I have experimented with their Metalic Red, Metalic Blue, and Insignia White on my horizontal stabilizer. My first attempt at painting the fiberglass pieces and the trimtab were not very good. After some sanding, my second attemp was better, but still not good. I had runs, orange peel, and oil rings. I could see just how nice the AFS paint would look if applied correctly, but there was still progress to be made.
Then, I got some tips from Andy Karmy, who was doing all of his fiberglass at the time. My third try at painting the fiberglass parts was pretty good, but not perfect. One problem was with parts falling over and ruining the finish. Also, I am painting with extremely cheap equipment and no paint booth. Obviously, this has nothing to do with the paint. It's just part of the learning process that you need to go through if you are going to paint a whole airplane.
I have fixed the problem with parts falling over (I built a rotating stand that will hold pieces as large as a wing), and the results are getting better all the time. The key is to practice until you have the feel, the mixture, and the environment right. I have no reservations about using AFS to paint the whole airplane. It really looks good when it is applied properly.
One thing regarding shelf-life which is supposed to be one year. I found that the white paint that had been opened a year before had started to harden on the bottom. I broke-up the hard piece on the bottom of the bottle, and thought everything was fine. However, when I got to the bottom of the bottle I discovered what felt like sandpaper on the top of the HS. You really should run the paint through a filter before you put it into the gun (just like the instructions say to do).
The Metalic Blue, which had not been opened, went on very nicely, even after a year. My suggestion is to order the paint when you need it, and use it once you open it, but it will definitely last the whole year if not opened. Note, that I live in Texas, and the paint sits out in the garage, which is not very good for paint.
BTW, the fiberglass parts that I painted over a year ago have been tossed around the shop quite a bit, and the paint has held-up really well, even if the application was not so good.
