If Vulkem is that stuff that was smeared all over the roof of our AS, I'm
not sure what the chemical difference might be, but the PL sealant seems
to be a little more flexable (tough) when dry and was easy to use. Was up
on the roof for Spring get ready and still looks great. Only time will tell.
The black color was my only concern, does absorb more heat. But then
again that "white" Vulkem gets pretty crudy looking after awhile.

So when is this..."old enough to know better" supposed to kick in?
