I would not waste my money on it. It is very expensive. I built my upper
cowling plug with it and was a major waste of money. The stuff expands
forever. Later after you start cutting in it, will start changing shape
again. Few times after I had the final shape perfect I went home. The next
day I had depressions in some places the size of my fist. Even after
glassing the surface it continued to distort.
Use blue styrofoam like the canard pushers use for the wings, or urethane
foam from insulation supply stores.
And BTW, the pour foam, when it sticks to something, forget it. It will stay
there forever.
