I moved to NJ from California a couple of years ago. I have a 77 k5 that is in good shape from a rust perspective. I have not driven it around alot since I brought it up here. Sooooo......is it truly possible to protective it from the rought northeastern winters? I do not see many of these older k5's (or any for that matter) out here so is all hope lost? The rain, snow, salt, humidity etc........how can I protect my pride and joy? Does the POR stuff really stop rust. Does it really prevent it even under these tough conditions?
