Yes, I plan to. I only applied the 3M tape to the passenger-side window so far. Running a razor-blade against the weatherstripping is a bit hairy since it easily cuts through the soft rubber. Funny—I just noticed that my GF's Fusion SE's window-trim is already blacked-out from the factory!
More badges to paint:
Since the Tamiya model paint was an utter fail, I'll be looking for a translucent epoxy-paint to do the fender SHO-emblems as well. Will do the same to the SHO/EcoBoost badge on the rear (which I've decided to keep). When I installed the PI-grille, I wasn't aware at the time of the all-black lower-grille assembly, so I still have the factory lower-grille there. Still on the fence whether I like the original (chromed) grille or the elongated, all-black PI-grille. If I keep it, I'll either tape or paint-out the chrome-trim.
Initially, I was really excited to get the Rotora calipers, but the brightly colored brakes will subtract from the car's PI/stealth-theme (also, it's not like I have the power which requires such a substantial brake-upgrade). Maybe I'll just paint the factory calipers in high-temp, gloss-black.
If I get really excited, one day I'll order the PI-taillights . . .
