Removing Dealer Insignias (Part II)

I tried removing the annoying dealer insignia thing the other night and it didn't go over too well.

I tried the fishing line trick and that worked pretty well. Most of it broke off as it was separating from the adhesive.

Like an IDIOT, I started in with a razor blade and had enough sense to quit before I did any real damage. I ended up using this stuff called Goo-Gone and a credit card. That worked pretty well until I got pretty close to the surface of the car and then it didn't seem to want to go any further... The car is a 95 civic and it's the original dealer's insignia, which means it's been fused to the car for about 7 years!

I 'd read quite a bit about the hairdryer thing, but I live in an apartment complex and:

A) I'm afraid to admit to my neighbors I own a hairdryer.

B) I'd feel like an idiot standing outside in the parking lot, blowdrying my car.

C) I don't have an extension cord that's long enough.

So, what actually happens when you heat up the adhesive? Does it just scrape off or just loosen up? If it's worth it, I'll buy a longer extension cord...

Next problem, in the process of getting this damn thing off, I did manage to nick my trunk a little and there's these little faint scrathes/scrapes but just on the surface. Anyone have any good good tips on how to get those out (either buffing or...)

BTW, sorry for the stupid questions. I'm half a moron when it comes to cars, but I hope to be a full fledged one very soon.

Thanks!
