So far no rust on the body, but surface rust has started on the underbody.

Did you inspect the lower control arm bolt on your car? I did that recently, and needed to replace both of those bolts. The passenger side bolt came out in one piece, but on the drivers side the head broke off. It wasn't a fun job replacing that bolt.

Thanks! I think the jury is out on how well electronic rust protection works. My former principal, who is a long time shade tree mechanic, swears by them. He gets them installed on all new vehicles. A few years back I convinced him of the merits of using an oil-based rust proofing compound in interior panels, rockers etc, etc and he adopted it as an annual maintenance item. He uses it in conjunction with the electronic module. His cars are all relatively new - none more than 5 - 6 years, so it's hard to tell which if any approaches stopped the rust. There wouldn't likely be any rust anyway as they are so new. I know that you will find a lot of debate regarding these electronic systems. Apparently they work very well on bridges and boats where a complete circuit is present. They theory is sound apparently, just much debate about how well they work in an automotive application.

I have not closely checked the control arm bolts but I did coat them in Rust Check Coat and Protect. Everythng seemed fine but I'll pop a wrench on them and check. Thanks for the heads-up!
