Ok so...2 quarts is not enough to touch up, do the grille and tail light guards, recoat the rockers, AND do the extra bumper.
Looks like I'll be ordering a gallon to do the front and rear bumpers - the front is sanded and primed with 2k epoxy - the rear will be waiting a week or so.
Had I not failed on the rockers when I did the original job, I probably would have gotten the bumper done too.
As a side note, the new coat of black is definitely shinier black than the original, but the truck hasn't been washed in a month. I just cleaned the spots I needed to hit.
After it cures for a week and I take the truck through the car wash we should see just how much fade there is after 12 months.
Pics incoming as soon as it's daylight.
