Outlined the perimeter of the trim with painters tape. Removed all the windshield clecos. Raised windshield enough to get access to the metal beneath. Ran a bead of Flex-Seal glue along the perimeter and re-seated and cleco'd the windshield. The glue is supposed to stick to anything, remain flexible, and be UV resistant, so I thought it would be a good thing to try. Once it cures, I should be able to score the edge and remove the excess with the painters tape.
