What also strikes me is the strange painting that has been done. I’m not any good with photoshop so apols...

A) Looks like only one top-coat has been applied, as you can still see the red oxide primer. So either it is pending another coat, or the current painting is inadequate.
B) The dappled grey/white area looks like it did in the earlier photograph, i.e. as if it has been sanded down but not painted at all. Also marked with the arrow, a fleck of oxide that also appears in the orig pic.
C) Here the paint appears to have been applied so thickly that it dried with air bubbles in it. Looking closer it appears they might have carried through from the previous painting. You can see what appear to be flecks of dappling on the corner of the rail, which to me suggests this has had one coat and needs another.
All in all a really sloppy bit of work. Going out on a limb I’d suggest that the paint marks on the black object to the rear have been left by a paint roller. If that is the case that is probably the problem. The work would have been much better done using a brush!
