[R-390] WD-40

[DW Holtman]

Hello,

If you google the MSDS for WD-40, you will find out it is a lubricant as 
well as a cleaner. It contains 50% Petroleum Distillates, which is a 
cleaner (such as Kerosene) and *25% Petroleum Base Oil*, I think it is a 
10 weight oil. It is not a pure oil,  but leaves a light coating of oil 
for protection on the surface. It is a great cleaner, but not so good 
used alone for oiling gears etc.
