New member, first post.
My new '06 e350 has light surface rust around the rain gutter. NBD but def needs to be mediated. My research has led me to a plan something like this:
1. wire brush/grind out the surface rust.
2. prime with a rust mediator for rust that may be lurking in the creases
3. rough up to prep for bed liner - or is an etching primer necessary?
4. Roll on bed liner over the rain gutter, maybe a 1/2" under the gutter
I've seen a few videos but still have a couple questions... does above sound about right? Do I need the etching primer? Any specific roll on products recommended or antirecommended?
