Hello forum, new member here. Just bought a 2019 Nissan Murano and the dealer was advising Waxyol rustproofing, stating Nissan discontinued factory rustproofing. I declined at the time of purchase, needed to research first. Anyone have any advice/thoughts? I live in norther WI, a lot of salt is used in the winter here on the roads. My apologies in advance if this has been discussed already. I'm new to the forum. Thank you!
