Paint Balcony Railing, Should I Do Myself or Ask Sponsor?

So the metal railing along my balcony is starting to rust and some of the paint is starting to wear out. I pay CC’s and so far there is no condo board because all of the units have not sold in the building.

The developer/sponsor is still the one who oversees the building. Do I have the right as a unit owner to tell him to dip into the CC to repaint the railings or should I just repaint myself?
