Chipped Kohler shower pan: Acrylic over cast iron

During the install of this pan, something was dropped and chipped several pieces off the Acrylic top coat.

Chipped area is approximately 1 x 6 inch. We managed to collect all the chips.

Several repair methods came up when I googled the problem.

Has anyone had this problem?

Any recommendations are appreciated.

TIA,

Rog
