salans7 Posted August 11 Share Posted August 11 I came across a pretty good video detailing the seam sealer along the firewall of the 1980-1997 F-Series trucks and Broncos. I personally will be doing what was mentioned in the video, as the seam sealer on my 1990 cab is long gone, and I can almost guarantee that yours is too. You may not have visible rust, but if your seam sealer is dry and pulling away from the panel joints, water is 100% getting in there, and the rust process is already starting.

viven44 Posted August 11 Share Posted August 11 Great educational video. I've addressed this leak based on discussion here... but that video really explains it well. Good save in the "How to" section. Link to comment Share on other sites More sharing options...
