I hope this is not a repeat... But for those out there who cant find marine goop.. In a pinch, the Plumbers goop, RV goop... And I am just certain even shoe goo is all the same stuff... It is all polyurethane glue. And darn good stuff I might add!
I have used them all, and they all work, smell(careful!) and look exactly the same... and they all stick and stretch the same..
I even mixed some on a job... and later couldn't tell one from the other.
Just a note..
