Although I have never had, or seen, an aircraft "powercoated" part
crack, I
have seen other powder coated steel parts crack, and the
powdercoated crack
remained hidden.

I wouldn't use powdercoat on an engine mount, for sure and not on a
4130 fuselage. But it came on the lift strut of a PA-18 and a
rudder-- both PMA'd.

I would use it on the step (or stirrup) that helps you get into the
cockpit. There you need it because of all the wear you would have on
paint.

I have seen it used with great esthetic appeal on yokes.

I would not choose powdercoating for a finish for anything I built.

Besides that, I can spray paints, myself, and can not so easily
powdercoat
anything.

Eastwood has a kit you can buy which is cheap and easy to use. You
just need an oven to cure it in once you've got it sprayed on your
part. The powder is attracted to the part by a high voltage.

I would not use powdercoat on highly stressed parts but it certainly
has a use in places on some aircraft, especially where the wear on
paint keeps you having to recoat it.
