Yeah I used Rustoleum on the mesh too, it was a flat black can of high-temp Rustoleum that's meant for painting BBQ pits
. Gonna leave the mesh and the plasti-dipped section of the bumper alone for a few months and see what happens, then decide what to do based on how well it holds up. The mesh I can just touch up (or replace if it gets banged up, it's cheap and easy now that I have the process down). If the plasti-dip ends up being way too fragile, I may strip it all off and re-paint with something else down the line.
