fogging spray?
There's a lot of hopla on fogging your engine. I'm in the south, so there's not a big deal in fogging, as long as your running the engine every now and then.
The reason we fog our engines is to provide protection to the internal components, casing, crank, connecting rods and bearings from rusting. With the atmospheric air, the constant change in dew point, the internals will slowly rust without it.
The M-2 Mercs only require to run a fuel stabilizer with a premix of 25:1 oil mix to coat the surfaces, but oil tends to fall with gravity, so anyone you have on the vertical surfaces of an engine block, find it's way to the bottom of the casing.
I use a Lithium spray on grease. It's not washable and will provide a barrier against moisture. I pull my plug wires and put them on their grounding strap, remove the air box cover and flame arrestor. Put the shifter in forward and go to full throttle. Then, while spinning the engine over, I spray the lithium into the cylinder through the PTO and MAG intakes at the carbs. Then, I remove the plugs and spray a little into each plug.
In the spring, when you start it up, the fuel will wash it off, but it'll smoke for a few minutes, till it's all gone.
I use WD-40 to spray on all my likages, including the cables and busings at the reverse bucket. Because WD-40 tends to evaporate over time, I usually go out there a couple times through the season to keep the linkage protected. Also, spary a light film all over the engine. This will keep the moisture droplets from forming and sticking to our engines surfaces.:cheers:
