A hand held propane torch will melt them off
NO NO, just funnin,
What the other boys said about heat and WD has always worked for me Good luck with it. Don't really know why they want to stick em on like they do
Spray the decals with WD40 and use a hair dryer on them, you might want to use a piece of fishing line or something with a good edge to get under the decal. You will lose very very little clear coat so that shouldnt be a concern. Wash, Dry, Wax and Buff when done.
