I can't speak for Israel, but when I blacked out my badges and grill (last week), I took off the front bumper and removed both parts of the grill to paint the chrome. For the front badge, I taped it off and carefully painted it. And for the back badge, I removed it by heating up the badge with a hair-dryer and taking a piece of floss and cutting the glue.
To paint them, I used Plasti-dip for a more flat black look.
