I have a 2016 Lexus RX450H Sport . I bought car used . It has 45,000 miles
on it . Looking for opinion on wether or not I should get it rust proofed . I live in
connecticut which uses harsh chemicals on roads . I am concerned about
electrical wiring because its a hybrid
You're likely to see responses here that vary from yes to no. Best way to know is to ask a Connecticut Lexus dealer about this. You do have to be extra careful about protecting hybrid systems under your conditions.
