Ok, so I moved from somewhere with no snow to somewhere with lots of snow and salt on the roads. My rock sliders are getting all rusty, and I'm worried about underneath. I wash the truck once a week, what else can I do to protect it? I don't want it to be one of those cars with flapping quarter panels and fenders.


P.S. I did a search and only found the thread about side rails not being able to rust because they're aluminum.
