More: Taping the edges!

I have NEVER used fibreglass before. I am going to build a teardrop - but angular - not rounded back (like attached photo).
I want to use West System epoxy and fibreglass tape along the top edge where it is most susceptible to water intrusion. I was thinking a 4" tape.
But what happens when the angle changes? Do I trim the tape so it lays flat (v-notch it)? Or stop and start again at the new angle? It seems to me that the transition point will make a weak point in the water barrier.
Your help is appreciated!
