First true PacNW rainstorm this weekend since we bought our 99 TC-24 earlier this summer. I thought the seal on the mast light might be questionable. The bracket (aft end of cabin top, center line) is slightly bent. And sure enough, I'm getting some droplets inside the cabin at the overhead cable penetration. Anyone know if the center raised (thicker) section of the cabin top is cored…or just fiberglass? Hoping I just need to replace the nav light fixture and reseal it...and not have to worry about moisture spread in balsa core.
