Re: Roof leaking by windshield and small rust hole. HELP!
If your seam sealer is cracked in the drip edge, then that is somewhere to start. You need to carve it ALL out. When you get it ALL out I would paint it with an epoxy prime or some POR15.(providing you take care of any rust) Then scuff with a red scotch brite pad. I would go with the 2 part Heavy bodied seam sealer since that is designed to be so thick.
Where is the rust hole over the door? In the roof, door jam, drip rail?
Pics are always good
