Hi all -- I just bought my first Jeep (yay!).. it's a 2000 Wrangler that was owned in the NY/NJ area for its first 8 yrs of life (now in NC). Looking underneath the car, it has a coat of red/rustiness all over everything. I don't see any blatant holes or places where things are rusted through, but I want to make sure I do what I can for it so it doesn't get to that point. So -- new Jeep owner here humbly asking for advice. Any thoughts on how to approach treating this?
