Using Sugru to Make Sharp Flashing Corners Safe

After a contractor refinished our deck they left quite a number of sharp rough corners in the flashing.  I tried silicone but it wasn't strong enough and kept falling away.

Adding a piece of Sugru to each corner (after cleaning) makes the job much safer and looks better too.  I applied the Sugru from the underside, forced it through the gap and smoothed the surface.

I only had black at the time I wrote this, I'll probably touch it up with some white enamel paint.
