Air in the pipe upsets the mix ratio. Air in the resin is mostly removed by
squeegeeing the excess out and tends to wick out along the fibres anyway.
It is a problem when mixing micro. The cure is probably special anti foam
agents in the resin which may explain why bubbles are less of a problem
with Superfil.
