I was washing my 2019 Ram and found rust starting on the top right rear wheel well, all the others are perfect. I live in rust belt so i deal with salt all winter but I'm good about spraying it off regularly. The rust is starting to spread the inner and outer panels but you can't see it unless you get down on the ground and look up. I sprayed some fluid film as best i could between the panels to hopefully slow it down but anyone have any ideas on keeping it from getting worse?
