It seems to me that Mylar may only be necessary on the top of the

The top side is the low pressure side Bob!

I don't think so, as the tail of just about every airplane or glider has
a download. *That's how they achieve stability. *So it's backward at the
tail, the top surface is indeed the high-pressure side.

Just to add to this "pressure" discussion, my elevator has a shape
similar to the trailing edge of my wing. The top-side is convex, and
the bottom-side is concave. Wouldn't that be a clue as to where the
high and low pressure areas are? I would think the convex side is the
low-pressure side, which is on top.

P.S. Any other thoughts on using mylars and safety tape on the
elevator gap?
