It's really easy to remove the badge. I used a scraper like this, as it's got a good strong pointy end too....
Start off prising between the badge and the plastic back. Be carefully not to stick the scraper behind the skin of the badge. Basically it's in 3 parts. The large black plastic mechanism part of the badge. A black plastic skin on top of that last part, and then finally the silver chrome plastic badge.
Just make sure you prise off the chrome badge and not the middle skin.
If you get it started at the edge first, you can then get the scraper point under the V and the W part of the badge and carefully prise away.
When you've done it once it's real easy
As for the black badge, I sprayed it myself years ago, but with the black skin behind a black badge didn't look very good on a silver car IMO.
