R Leo,
Thank you for posting the pictures of my sunroof drain stubs.
They are seriously rusted and I'm concerned about their soundness. I need to inspect their insides as well. You brought up a good question. How do the rear drain stubs look? I guess need to think about removing the headliner.

Jimsmith,
I have heard of por-15 before. I've used extend to neutralize rust before. These stubs are rusted quite severely and may need more work.

Has anyone pulled the sunroof drain pan ?

Any help would be greatly appreciated.

Thanks,

Mike
