For my P5 (may differ slightly from MSP):
"Mazda" and "Protege5" easily pryed off with a heat gun (3M tape), be careful not to scratch your paint (masking tape around a screwdriver helps)
--NOTE--
Removing your badges will leave holes in your trunk, painting (and body filler) is one option, living with bullet holes in your trunk is another.
BTW welcome to "El Forums", that's spanish for "The... ...Forums!"
