Thanks for the info Dan. I agree with your assessment of the angle tip and full sleeve caulk gun.
Kevin, your experience gives some hope!
Now that I have the windshield gasket installed, it's time to seal it to the body and the glass. I only have this windshield to do, so I'll just suck it up and use what I have available to finish the job. It looks like I'll have some time mid-week, time to get it done.....
