I debadged my white VX Commodore S a few years back...
Tools:
Hairdryer
Fine fishing line
MF cloth
Eucalyptus Oil
Method:
Heat with hairdryer
Slowly "floss" the badge off with fishing line (rehating with hair dryer as needed)
Swab/wipe with Eucalyptus dampened cloth
For extra after removal care, polish and the wax the area straight away to protect your paint.
