roof drip rail caulking

[nevada]

Anyone know what type of caulking to use above windshield drip rail? We dug what was left of the old stuff out to expose and weld shut a few holes in the roof.

I used ACDelco 10-2013 Body Joint and Seam Filler Compound, and a rag with mineral spirits to smooth out the places where I didn't have a steady hand. Here it is on Amazon:

Most guys use a self-leveling seam sealer. Most are two-part epoxy. There are several brands but 3-M, SEM and Eastwood seem to be popular choices. If you go to your paint dealer, they should be able to get you the right stuff.

I used the 3M 8307 two-part self leveling on the horizontal surfaces. It dries in less than 5 minutes so if you run a tape line, remove the tape as soon as you lay the sealer down. It is sandable/paintable in 15-20 minutes. I used 3M 8308 two-part heavy-bodied on the vertical surfaces. It is much thicker than the 8307 and stayed in place without running. You need an appicator gun, I found mine on ebay for $25 shipped.
