Been a long while since I have posted. But have a question. Working on finishing fixing a leak. Got to the trim on the underside of the over cab. The trim had a layer of butyl putty tape in it, but from what I could tell, it was no where near enough to do any good. For those that have done this project before, how thick do you want they butyl putty tape layered in that trim to be effective? I was thinking 2 layers thick, with a third layer at each screw hole. To make sure for contact with both surfaces and a good seal at the screw hols. What are your thoughts?
The attached picture is with it setup like it was originally, with one layer and a second at each screw hole.
