The purpose behind fogging is to put a thin film of oil on the internal engine parts to keep any ambient moisture from rusting or pitting the internal parts. Keep in mind on any 2 cycle (OB or PWC) when you fog the motor (given the workings of 2 cycle)
everything inside gets a coating. Not just cycinder walls and piston tops, but also crankcase walls, connecting rods, all bearings etc. Of course when you fog a 4 stroke only the top end gets coated, but then again thats why you have just changed your crankcase oil and run the engine to get a coating of fresh clean oil through the lower end of the motor. Now knowing all the facts......what sounds best to you?
