Removing 3M Automotive tape residue

I took my 3 piece spoiler off, and am undecided if I am going to be putting it back on or not. What the best product to use to get the tape reside off my car without damaging the clearcoat/paint?

I used WD40 when I removed the side skirts on my DSM:D

This works great:
3M™ General Purpose Adhesive Cleaner

Goo gone also works well in removing adhesive residue.

I have always used goo gone with no problems.

Best thing I've used is the 3m eraser:

I've tried all types of adhesive removers at work, but this works the best and the quickest.
