How can I remove a really stuck screw?
I have to return my license plates to DMV by Friday (they expire!), and am finding it next-to-impossible to get them off my car! First I tried unscrewing them with a solid/thick flathead and neither screw would budge (there's two; 1 on each side of the license plate):
So early this morning I practically emptied a small can of WD-40 on the screws, both of them, on the front of each screw (and around them). Additionally, I pried back the license plate away from the car, and sprayed WD-40 on the back-side of the plate, around the area where the screws might be rusting/welding onto the car underneath the plate. I let it sit there soaking in the WD-40 spray for about 40 minutes, which according to the instructions, is more than enough time for it to take full action.
These screws will not budge! Either of them!
I am junking this old car, so I'm not too concerned about hurting its exterior, but I'm at a total loss as to how to get these screws off. I have a hacksaw, but the width ("curf"?) of its blade is too thick to fit between the bulky head of the screw and the license plate (preventing me from being able to cut the head off). Not to mention I don't think I could use it anyways, because the license plate area is recessed 3 - 4 inches inward from the rest of the car's exterior, and I don't think I could fit my hacksaw into the recess.
