I've seen corrosion like that on most NEMA 3 rated stuff, in Puerto
Rico, Florida, and Hawaii. Close to the coast, any regular steel is
going to have problems. Powder coating is better than paint, but its
still steel underneath. Changing the hardware to 416 Stainless might
help some, too.

We have five PF16 installed outdoors at a home. It has been only 2
weeks and I'm seeing rust forming around some cover screws (both the
top cover and front cover). The brackets are also showing some rust
spots, and under the rims of the top cover I'm seeing rust spots that
look like they are from small metal shavings. We also found minor
rust around a prepunched knockout immediately after removing the
protective plastic cap.
This all happened after they had been mounted outdoors for two weeks,
but no conduit had been installed yet and the top covers hadn't even
been opened once.
Is anyone else seeing these issues? I'm pretty concerned that my
customer won't accept this early defect, and I have lots of outdoor
installations planned for other customers.
P.S. This is not a coastal location (although all of Florida is kind
of coastal). Regardless, it's IP65 and should withstand a typical
outdoor installation.
