Hello there, I have an issue with the sealing of my trunk/ rear lights on my 69 Satellite. The tail meets the rear quarter and there is a gap between the two parts (as seen in the photo). Right now, rain would run directly to the taillights. Question: how should this gap be properly sealed? What stuff would go into that seam? The car is painted and I hope, that sealing the gap will not destroy the paint? Your help would be greatly appreciated!
