Hello I have a 2016 RC 300 F Sport. Purchased in March of 2017 with 3,000 miles on it. This car spent the winter of 2016/17 on a CT dealers lot. I live in Vermont where salt on the road and the use of brine as an ice inhibitor are pretty common. i would like to get this car undercoated. I have contacted two Lexus dealers that have basically been unresponsive. My question is if I cant find a Lexus dealer to do the undercoating and I use a local shop, do I risk voiding the cars warranty? I am specifically concerned about spraying over sensors that might make them inoperable and hence impact the cars diagnostic systems. I would appreciate any experience that other owners may have with this. Thanks.

 

Check out Krown...My opinion best stuff out there. It won't affect any sensors. Vehicle manufactures for rust perforation are useless. They will say it started from a rock chip and ate it's way through. Do the Krown thing and you will never have an issue.
