I bought my 2022 Toyota Cross L AWD in Florida. I will be moving to Minnesota and am unsure if I need to get rustproofing and/or undercoating to protect the bottom of my Cross. I have been reading different websites concerning my issue and came across rxmechanic.com, and they say:

FAQs
Q: Are undercoating and rustproofing worth it?
If you’re contemplating, “Is it worth it to undercoat and rustproof?” Undercoating and rustproofing are vital for older vehicles. This is because both applications help to protect the car against the abrasives on the road that are capable of causing corrosion on the vehicle’s underside and other parts. However, modern vehicles do not need undercoating or rustproofing because they come with corrosion protection from factories to keep corrosion at bay for their lifespans. Manufacturers now ensure that they critically design every component of their vehicles to ensure they reach their lifespan without any further add-ons. But unfortunately, some modern car owners still opt for undercoating or rustproofing to protect their cars against corrosion.


Does anybody know this is true with the 2022 Toyota Cross, or does anyone have knowledge of a T. Cross in Minnesota-type weather?

I have never undercoated any of my vehicles. I always had weather tech mats, keeping that floor dry inside is key IMO. I've seen vehicles that have been undercoated religiously through their life span and I found it to be worst. almost like a greasy rusty build-up.
