Yes, it has that stuff on it. Good sticky tape can lift it off, or you pick at it with your fingernail. The only good aspect is that I can remove marked lines after the fact.
I have a better idea than drain holes - a sloped panel "roof" inside the strake to shed water out. Even with drain holes, in the winter it is going to freeze - and that would not be pretty.
I got the left side more or less to the same level as the right. I cut off the excess fabric at the top, as well.
