Use West Systems resin & hardener, add Micro Balloons until you get about the consistence of Peanut Butter.
When dry it is very sand-able.
This is what they use on the bottom of real boats under the water line to repair a hull.
I used the same stuff to blue-print the bottom of my DF-33 and some minor repair on my real boat.
