So I'm getting my new SVT at the end of the month (Comp Orange!!!!!), and she has a few things that need to be worked on. Undercarriage is super clean though, no rust at all (saving for the rear subframe, has a tad of surface rust, but nothing out of the ordinary). I'm not very knowledgeable about body work in general, but I'm wondering what the folks here have used for undercarriage protection, and what recommendations they can make. I was thinking of using something like rhino liner after ensuring it was completely clean, but given what that stuff is, I'm not sure if that's the best of ideas. I'd like something I don't have to check up on every three months, but many once every couple of years would be nice. I've heard of some rubber spray on stuff that you can use, but can't seem to find any good information on it. Anyone have any ideas?
