Pulled the louvers apart, sanded, repainted, then got new rivets and hardware. They turned out nice, as with everything there are a few flaws.
Making an effort to spruce up the front bumper that should be replaced, the metallic spray paint is a PITA but after some clear coat it aught to hold up.
Only after cleaning up the car does the severity of this front bumper situation rear its head. The mounts are bent and with no trim its looking horrid, since finding said trim hasn’t bore fruit ill likely end up making new mounts that bring it closer to the car and hacking together some trim bits out of steel (might force me to buy an English wheel)
