    Purchased the truck a little over a month ago, and need to stop the rust from spreading over the cab area. It begins around the windshield area (front-center) and will not stop if I don't act. Other areas in the vicinity appear to be "bubbling", what should I do?

    Bubbling means the rust is underneath the paint already. I would strip it down I metal and respect it. Or use a rust converter.

    Bubbling is bad, though, and it'll get worse if not addressed.

    What is the best method to strip, and what is the best way to cover and prevent?

    Rust creeping out from beneath the windshield molding means lots of effort to fix. What causes it is glass shops cutting the windshield out and not putting primer on the scratches they have made. Moisture sits in there and eats your truck immediately, constantly.
    It's frustrating- those guys all know better, but the extra 2 minutes it would take are too much effort, I guess.
    Best case scenario: the glass comes out and amazingly, the pinchweld is still largely intact. POR-15 or Rust Mort in the pits, fibreglass or body filler for the cosmetics. Paint whole roof.
    Worst case scenario, the pinchweld is totally rotted away. $$$ or, if you're capable, hours of fabrication. Body fill, paint whole roof.
    Sorry to break balls like that, but I think that once the glass is pulled it is going to be bad news...:(

    Thx, which corrosion inhibitor would you recommend? And as for grinding, do you suggest sanding or some other method?

    The only way to truly stop rust is by sandblasting

    I guess I will grind/sand about 6" back from the windshield and fill apply a generous coat of paint.

    This is a common problem on these 1st gens.

    Here's mine with the windshield being replaced a few weeks ago. Mine has had this issue going on for several years now

    This is an old thread, but i started it so i figured i would update:

    Water was leaking through the roof so about 6 months ago, i applied silicone and it has held up very well. No leaks since.

    Did you ever end up repairing the rust? My roof looks similar (not as bad as yours but same idea) and I'm planning to grind it down to bare metal, then apply rust prevention/rust inhibitor of some sort, and then repaint.

    If you repaired it, could you share your experiences? Any tips/tricks/things you learned along the way?
