I really like what Stellamon did, filling the trench with white caulking (putty? polyurethane adhesive??) but it looks like a nightmare for the next glass replacement?
Is there a peel-out product that could be caulked into the gap, maintain a seal, but be pulled out easily for maintenance? Something that behaves like a 3M Command Strip(tm)? (memories of using beeswax to fill checking on varnished wooden spars...)
Background: Permanence isn’t an option, since a windshield in Alberta seems to accumulate a chip every month or two, goes maybe two years before a crack opens (from a failed chip repair), and will be ready for replacement in three to five. It’s normal for marble-sized stones to be tracked onto highways from rural roads, or spread with winter sanding, and be kicked up in your path. My current windshield made it less than a week before its first bullseye... has been repaired a half times, developed an unrepairable crack last spring, and has finally split in half this winter. Three years cradle to grave. I’ve got a bit of rust showing so I’m evaluating my options.
