...then 2 steps back...
Napa had their cheaper 3M kits 40% off, but of course the largest kit, with this applicator, which was in-stock, was $28:
I wasn't going to pay 125% more for it, so I bought this awesome thing for $3:
I posted the picture because the manager and I couldn't find it on the shelf based on the on-line picture.
The 3m sandpaper is awesome. Why can't I buy that separately?!
I just tried the get the parts with bad clear coat and then feather it out, but the battery in my cordless screwdriver, which I just charged last week, quickly died, so I found my drill and tried to exercise trigger discipline.
I also tried to keep the drill and the hose as far apart as I could.
Unfortunately, one spot between the headlight and the turn signal was still dull. I finished wet-sanding and was using Plasticx, but I didn't move the drill back and forth enough and\or squeezed the trigger too hard, so I melted a few spots on the lens and shredded part of the foam pad, so I needed to sand it over again.
After all of that, for the second time today, it looked about like it did before I tried to clear-coat it, but now I need to preserve.... uh... 9 days of work?
Paint-protecting film is sounding pretty good!
