My experience with Gorilla Glue is exactly as Scott describes. It is certainly strong enough to hold, but it does need to be carefully clamped, and even then, there will be some oozing as the glue expands and sets.

My repair job has held up for over a year now, and has been through all sorts of weather.

Good luck,
