Loctite make some stuff called "Freeze N Release", which is basically a combination of freeze spray and plusgas. Halfords / car spares places tend to sell it. It's really useful as it lets you get a big temperature difference between components without resorting to heatguns and blowtorches.
And Plus Gas always beats WD40 in my book, but WD40 is better than nothing.
