About all WD-40 is good for is displacing moisture.
PB Blaster is a true penetrating oil. Track some down and try it- you'll never buy WD-40 again. I only buy WD-40 because I can get it in the tiny aerosol cans to throw in the glove box in case I get water in the distributer. It's about worthless for anything else.
Being in Canada, Kroil might be easier to find- it's just as good, and some would argue it's better.
A Heat gun will work- propane torch is faster, but you're working on metal that you've just soaked in petroleum products- be careful.
