Here, I am told the procedure is to spray the oil on after several days
without rain (assuming you can find several days without rain in VT), then
take a quickish drive down a dirt road to "set" the oil. I can attest
that doing this every fall builds up a nice oily "cake" except where the
spray from the wheels is directed right at the metal. Only sandblasting
with "Black Beauty" makes you dirtier than working under a 10 yr old car
that has received this treatment annually.
