Anyone interested in 83 Pace Arrow Tear down and Rebuild?

I know exactly what you are doing, it is a reverse pattern and the fiberglass goes on the outside of the box.
What I am referring to is making the bottom of the sink with rounded corners and the four corners radiused so that there are no 90° areas, also give the bottom a slope towards the drain hole, we have a deep sink in the kitchen with the drain hole in the far right corner and sloped, no water remains in the sink.
