Depends. Here in the land of over-regulation, powdercoating is not allowed
unless it can be proved to crack when the surface of the underlying material
cracks. Having tested several types, I am pretty much convinced that the
hard polyester powder coats are fine. So are our CAA, who permit them on
aircraft structures, engine mounts etc.
The nylon ones definitely aren't OK though. I am pretty sure that cheap
nylon podercoat is what's used on domestic garden goods, the sort where rust
bubbles up under the coat after a few years.
