Welp, I did it. I still need to wet-sand and blend the paint, obviously, but the Grimmspeed WRB is a perfect factory match and even with all this orange peel (again, I know I need to do the wet-sanding!!!) it's virtually invisible from farther than maybe 3 feet away. HUGE difference.
I masked up to the body line on the "lip" area and used two thin coats of primer, three thin coats of WRB, and three thin coats of clear. I sanded with 220 - 300 - 400 grit between primer coats but did not sand afterward.
The big scuffs on the side of the bumper will mostly buff out and I'm not as worried about them as I was the big gouges in the bottom of the front bumper.
Not bad for like, $45 worth of paint/tape/etc.
(thanks to @
DarrenDriven for letting me use his garage!)
Car will be wet-sanded and machine polished either this weekend or next depending on my schedule. Will report back if folks want.
