Ok so I didn’t see any threads that mentioned these two items in a Search. I saw these two items on a couple of those “weekend wrench” shows. Anyone have any experience with either of these?
I have no actual info on the rust protective thing. However, a friend’s parents car had one of those systems installed, and the car had no rust on it, which was rare for a GM car from the 80s in New York. As was mentioned though, if it was that easy to stop rust, I imagine it would be standard equipment up here.
