Rear bumper protector for 1999 GX470

[Jayro]

Is there an aftermarket solution for the painted on rear bumper protector for the 1999 GX470?  Most SUVs simply have a black plastic cover that you can simply remove and replace once worn out.  Even newer GXs have them - so in essence, if it’s worn, you must repaint the black area/the entire bumper.  Would be appreciative if anyone knows of an aftermarket solution.  I love my GX, but this design choice is annoying!

Not sure, apart from repainting each time but maybe using a thicker (enamel based) paint in the areas that are most affected by wear?
