Agreed, IMO WD40 and other sprays have little or no place in camera repair. As a matter of fact I don't even own any. I use a good quality penetrating oil either on the tip of a toothpick or in a hypodermic syringe with a fine insulin needle installed.
My soldering irons are all in the 5-15 watt range, which is probably why I've had little luck with the heat/cool method. I'll have to try it with a bigger iron someday.
