I plasti-dipped my badges, the front grill, and the rear piece just over the tailgate latch, all while still attached to the vehicle. Plastidip is nice because you don't have to worry about taping too much and Is why I chose to leave them on. If you remove entirely, then maybe go ahead and paint and clear coat for protection
I have some pictures that I can attach later when I get home. I loosely taped off the area around the badge, but don't worry about getting too close with the tape because the extra will come off easily (it will make sense later and with the pics). Use some newspaper as masking around the entire area to prevent overspray, and just go at it with like 5-7 coats. I think I waited 30mins-1hr between coats on a cool-warmish day.
After spraying, I would recommend waiting a while before peeling back the surrounding bits of plastidip. I removed the extra bits on half of the badges about 3 hours after my last coat and then came back the next day to remove the rest of the extra bits - complete night and day difference. After sitting for a while it sticks together much better and the extra can be removed as one piece instead of a bunch of little stringy bits. Use a toothpick or something wooden to remove the extra inside the letters.
edit: so apparently the pictures I have aren't as good as I thought. Could have sworn I had some pics of it all masked off, but apparently not.
Probably the best one I have of the tape. This is before anything real happened and you can see how I did the tape. I might ever suggest leaving a bigger gap around the letters to make peeling easier.
After spraying down the letters. Plastidip kinda has some orange peel, which I don't mind too much. One thing to note is that it doesn't seem to feel dry for like 2 days, but give it time and it will harden up.
Overall back shot. At first the trim piece over the rear handle was giving me moustache vibes, but I eventually got over it and like it better than colormatched. I plasti-dipped over the Toyota logo and then peeled that off. On the front it was easy enough to remove and then reinstall.
This is how the front turned out. Just masked around grill and bumper and put some newspaper behind the grill
