How to remove a spoiler from a car

I hope this is the right forum to post this in...I looked and couldn't find a more appropriate place.

Anyways, how would I go about removing the spoiler from a G35 coupe? I figure there would be holes left over after removing the spoiler, can I fill these in myself? Is it difficult? Or should I best leave it to a shop? And what about the colour?

I find the spoiler kills the lines of a G coupe.
