This is good advice from Chris. Follow the
instructions of the manufacturer and you’ll have as good a product as possible.

Some
primers and paints cannot be sanded prior to top coating. I used a
non-sanding primer, for example. It was only used for adhesion and is
very thin. It rolls up like roller bearings if you try to sand it.
Also, pearlescent
color coats can't be sanded prior to clear coating. Doing so ruins the pearlescent look.
I would
suggest reading all instructions and trying out any new technique prior to
painting the actual airplane parts.

I made a rotisserie for the wings (sent a picture to the LML). The
wings were painted in one fell swoop. After the primer there was the UV
protector, then white, white, white, pearl, pearl, pearl, clear, clear. The
white through the clear was made in one sitting with the rotisserie. You can do
the same for the fuselage if you want only one color. Otherwise, there’ll be
several sessions of painting.
Hung all parts horizontal. The edges will buildup paint to make a
lip and there’s not much you can do about it. I think it’s a physics problem.
Nevertheless, you can remove that lip of paint from the edges if it’s done
carefully. Make sure the edges are sanded flush of primer. Then when you add
paint, the only lip will be paint. You can sand that “flush” like the primer.
Then clear then sand flush. But every layer has to be sanded flush at the edges
before the next change layer is made. Make sense? I did not do this process and
suffer from the little lip in fear of sanding off the clear, pearl, white down
to the primer.

I
hung or supported every part such that I could paint all
of its surfaces at one time. Vertical surfaces are certainly more
difficult in that you can't afford to go too heavy in any one coat. Once
it runs, it is all over. Spray all your test panels vertically for practice. The build up along the
edges sounds like the material is going on too heavy. Reworking
edges and corners after the fact is very risky. It is very easy to break
through all the way down to primer. It is best to practice putting the
paint down the way you want it and avoid post-painting fixes.

I could use a few
tips from those of you with painting experience.
Do you get a better result when spraying control surfaces by laying them flat
or by hanging them vertically?
I tried spraying a couple of test panels and in my case, flat seems to be best.
But I'm getting a slight build up of material (several mils) along edges.
Is this typical and do you just clean up edges and polish when the part is
done?
Thanks,
