Reasonably easy to work with
I used Sikaflex-715 to address some leaks in the roof of my RV. It looks like there was a bubble in the original sealant that resulted in a slow leak when the RV was parked at certain angles. I found the 715 to be easy to apply. It was runny enough to flow into gaps without flattening out too much. It left a few strings at times, but not a problem. It was easy to clean up messes by rubbing with a dry rag. Cure took a few days. After 3 days, it is soft and sticky, but not going anywhere. It looks like it will seal well.

Perfect for my RV
This is the original sealant used on our RV. The projects I have used this on worked very well and seem to be very durable so far.
