Took off the skid plate today while getting ready to do an oil change and noticed some rust on the radiator support member. Looked closer and once I peeled the flimsy foam piece they put on there for what I'm guessing are sound proofing purposes (prevent skid plate from making contact?), I found quite a bit of rust! I ripped that foam piece off, it was wet and apparently has been trapping water and whatever else got in there. Wire brushing and Rust-Oleum is on the agenda for tomorrow. My 4runner is a 2016, and aside from this rust-free, some minor surface stuff here and there notwithstanding. It's far from neglected as every time it sees road salt I get a hose to the undercarriage first chance I get.
