Something else that is inconsistent with condensing ice forming on the location in question is that such ice typically forms in a clearly crystalline form, a kind of hoar frost. The white stuff on the strut looks smooth and globular. It might be said that the stuff is melting, but then that is inconsistent with the fact the underlying and nearby globs have remained in place for 84 days, and also appear to have accumulated a dust covering.

effect with railings here in arizona in the dry dry winters.

could that be frost?

Could be, but it seems to me unlikely, given there is no frost on anything else. A very light morning frost does occur on the ground there at times. If anything, the "before" picture looks like the ground is lighter, so it
should have the frost.
