Had my wheels off today.. looked at the spring perches real good.. on a very lower seam I saw a very small spot of "rust water".. the car was in TN all it's life with no snow at all.

What do you guys think of smothering the entire lower spring perch with something like POR-15?? I am VERY concerned because I travel alot through the snow and salt in the winter.. Right now the car does not have a one ounce of rust anywhere.
