I think it is LeakySeals on here that brought up RP-342, which is basically cosmoline in a can. I've decided to try that for now. Fluid Film isn't bad, but it isn't great. I found I had to respray in the middle of winter--but I drive a lot, so maybe I'm not a good datapoint (500 miles a week). Maybe a layer of that, with FF touchups? not sure. Current crop of cars I don't think I'll take past 10 years anyhow, so I don't want to think too much about it.
