Yeah I'm going to try getting some sort of heat onto the decal to loosen the adhesive. I don't have a portable hair dryer but I suspected that would be very effective. Nobody in my family is really handy, so we don't have certain "standard" garage things. We don't even have any flat razor blades around the house.
I was also planning on going to the auto supply store to see if they could help me out. Do you think it would be safe to use lighter fluid? I've read that's also pretty useful. I'm just afraid to use it on my car, even though it's only the windshield.
