Don't remove it! Just put some phone books on the front seat, just high
enough so you can look over the spoiler. It will also give the people
who you pass on the road the appearance that you are a big badazz.
Seriously go to Home Cheapo or Lowes and buy some plastic "push rivets"
(they look like mushrooms) and use a dab of clear silicone to seal out
the weather. Paint rivets with a close match "plastic only" paint,
prior to installation. Total price should be about $6.00 as long as you
don't have to drive 100 miles to the store.
