RE: Sealing Monokote edges
The stuff I use is called clearcote.
I don`t know if is available in the US, but it is a fuel proofer that you can put on with a small brush.
It dries within a couple of minutes and is almost completley transparent.
Just brush it along the joins in the covering and they will never lift.
It doesn`t change colour over time, or if it`s left in the sunlight either.
