OK, just another update.
In the past, during the summer with new HS2, I have had good results at removing mixed air from HS2 by using my food saver with the vacuum canister. In fact, it was really good.
But, no so much during the winter and with older HS2.
I turn my heat down to 55 in the winter in my man cave. This thickens up the HS2 a bit. During the summer my man cave runs about 85 degrees, and that tends to thin the HS2 down a bit, and speed up the final cure.
I know that some will have read my past post about using the food saver, so I wanted the final update clear. The food saver helped, but it did not remove even half of the air.
