Grip Screws

How do I loosen a rusted screw/nut?

I just bought a used car. While removing the previous owner’s plates, I found that one of the screws was badly rusted and impossible to unscrew. I’ve tried WD40 but it hasn’t worked. Does anyone know any tricks, solutions, formulas for loosening a stubborn screw? The nut is on the outside of the plate. The head of the screw behind the plate (and it is rather difficult to get a good grip on this screw with the screwdriver since it’s behind the license plate). Thanks for any serious suggestions.

IF you don’t want to risk damaging your car and plate, you should have a profressional remove the screw for you. I would at this point use a cut off wheel, but you have to be carfull not to damage anything else.
