One of the suggestions of the mfg is to draw a vacuum on the mixed urethane to degas it as much as possible before pouring. With a bit of mods, I can have that capability with my pressure pot and AC vacuum pump. Am getting stuff together to make another lid so as to make a vacuum chamber. Will experiment with the remaining product left in the open container -- Don't think it is enough for another full sill but will at least be enough for a test to see if degassing first helps. Trick will be getting it degassed and poured within the open pot time.
