After removing it you will have 2 holes in your bumper, and the tabs will be unusable after removing them. Some have used black screws or even chrome ones to fill the holes.
Ha, Nelson, I did the same thing with my F150, I was parked right up against my buddies garbage can which had a huge rock in the bottom. When I left his house a few hours later I couldn't see the can over my hood so I put her in drive and crack. Same thing, came off fine with no scratches.
