I am looking to paint the underbody / frame of my non LBC. The vehicle
will be used as my winter transport and subjected to road salt. Vehicle
frame has factory E-coat reasonably intact (local areas of nonscalely
surface rust). Vehicle is 8 yrs old but has seen minimal road salt to
date. I have never used POR - 15 or Corroless (sp) as mentioned by other
listers. Would this be preferable to using PPG DP90 epoxy primer as a
corrosion inhibitor? Looking for suggestions from others that have painted
the undersides of their winter vehicles that are exposed to road salt.
