I will post a picture when I can get back under it. This stuff looks factory original/ I thought the same, that they didn't have the spray on stuff back then but after taking a good look, either it's factory or whoever applied it was a magician, because it looks like it was painted on, every crevice is coated with no overspray at all.

I can't help with the leak, but I just bought an 86 Escaper and I also have the "floam" stuff all over the underside of my rig. It's in great shape and does NOT appear to be something applied aftermarket, it's too smooth and appears to be original to the coach.
