Agree. Heat and shock from wacking it when hot can bust up the cooties a wee bit to allow some of the penetrant to sink in.
Spraying penetrant on a cold joint could take days and days.
Once a disturbance in the "force" has been delivered the penetrant will do it's job. That's one reason why I reef on it clockwise as well as CCW.
If you have the right amount of heat, though, that's all you need. You can bust it loose with a crescent wrench. MAPP gas/propane won't get you to that point usually.
