Morning. I leased a 2019 Silverado and have been driving it for about a year. . The plan was to buy it out of the lease early and lift it. I had an appointment set up to meet with the dealer for purchase, put a lift on order, had some LED taillights come in too and when I got under the truck to run their wiring harnesses, I couldn't believe how much rust was already on the truck. After looking around online it sounds like this is pretty common on GM trucks due to the wax coating that they use to dip the frame. Now I'm at the the point where I'm considering scraping the project and just getting a Ford or RAM next year when the lease is up. Of course you may get some rust on an F150 or RAM too but I can't imagine it would be to this degree already. In fact I've searched online for issues with other two manufacturers and have only found reoccurring posts on the 2019+ GM trucks.
My question is, is this no big deal and something I should just treat with Krown once a year and forget about it, or is this a real cause for concern? Only two photos are included but the entire underside looks like this.
