Hi guys. I have a newish Savana 1500 passenger van. 2013 with 50,000km (31,000mi). When it rains hard, water pools inside the vehicle, under the column by the rear door. I traced the leak to a crack in a body seam above the doors, where the roof joins the end of the rain gutter on the passenger side. The sealant there has cracked and separated. The driver side is cracked too, but not yet leaking. I'm curious if anybody else has failing seam sealer in their body joints.

 

looks like a good place for a fiberglass patch.
