    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.

        I'm pretty certain that not all foams are = equal. I used the pour foam and never experienced any of the problems = you mention. Within 10 minutes it would reach it's final size and shape = and would not move or distort in any way at all. It was easy to sand to = shape which would remain exactly as I left it, with or without = fiberglass over it.

        I actually enjoyed working with the stuff. = Maybe I just inhaled too many fiberglass fumes :-). I don't remember = the brand name of the stuff I used (I'm at work now so can't check), = but it was only $40CAD for 2 liters (1 liter of each part) which = expands into a ~gazzilion cubic feet. Since so many others use it = successfully, I guessing you may have had either a bad batch or the = wrong stuff.

    And BTW, the pour foam, when it sticks = to something, forget it. It will stay
    there forever.

I agree with this. = If you can't reach it with a scraper, it stays.
