Expansive rust is definitely a problem on machine tools and tooling in FL, and I've seen cams with spalling from sitting.
For machine stuff, lanolin and camphor do well if mixed in mineral spirits and sprayed, for larger areas I cut it back with the yellow/tan toilet bowl wax rings (beeswax?) or various other wax-ish compounds like paraffin to adjust hardness or temp preferences.
Many of the plant voc terpenes behave similarly by occupying reactive metal surface area, I use the ones that IMHO smell nice.
I think Ballistol uses Tea Tree oil but oof the smell.
When I have metal in the white, Camphor is the go-to. It's excellent in compartments as well, the tighter the better.
I use 1kg yearly camphor in ammo boxes, tool boxes, safes, anywhere metal is stored I put camphor to slow corrosion by contact with atmosphere. Five stars, if you remember to replenish it.
Fluidfilm is the best rattle can corrosion inhibitor I've found *when corrosion is provided by the base oils.
The other good ones contain calcium sulphonates, such as what's replaced lithium in light greases, and in Rem Oil.
I'll go back to look at the SDS for that CRC fogger. Some of their special purpose shmoo is excellent.
On the water, I disagree. Short trips and low operating temps are known to accumulate water in the crankcase/oil.
Because water in fuel exists, fire makes water, and certain engines can leak fire and water into each other without permission.
My air cooled 2 strokes run hotter than my water cooled. These are my observations.
YMMV such as the neighbor who idles his leaf blower and never gets up to temp. (if we demand an exception)
Does anyone prefer a certain base oil chemistry, or adpack to a certain base oil, as fogger?
Ex, non-castor. FluidFilm is definitely lanolin, suddenly I want to run some through an engine to see how it smells!
Is there an old-timey product or home brew, such as the "Ed's Red" of the gun community?
As a followup, what temp do people fog at? Good and hot? Or cold, so the shmoo coats real thicc?
