Well, Jeff. You and I know it isn't the best way, but it was probably the expedient and lowest cost way to deal with it then. Of course, 18.00 a box for strip caulk these days, and I'll bet I use most of a box. I considered using the mastic tape that is used around expansion valves and such for AC. It seems easier and a cleaner way to do it.
I just wanted to make sure it belongs inside around the edges of the lamp, hidden under the lamp supports. Many stories about the exhaust fumes coming into the vehicle, so now is the time to head this issue off at the pass.
