I just read the comprehensive directions w/pics in another thread earlier. I basically get the idea now. But my friend who owns an 02 honda accord coupe recently cleared his corners as well. He said he used a hair dryer, a knife, and silicone. Is it possible to heat the seals on the Acura headlights rather than putting them in the oven? I really don't like the idea of leaving my headlight in the oven. I'm not too sure if my oven still works right haha. I have heard stories of someone actually doing this project while their headlights were still on the car. Anyways thanks for the help.
