First, GOOD CATCH, you saved yourself a LOT of grief and money by finding this early!!
This material will work too, and does not dry and crack over time like Dicor does.

VERY easy to work with, flexible and long lasting stuff.
I used it on all my edges, seams and all roof penetrations as a precaution when we bought a 3 year old camper 5 years ago.
No leaks, No problems so far.
