[pct-l] To waterproof or not to waterproof (ye old sleeping bag) that is thee question.

[Paint Your Wagon]

OK,
Experts, newbies, wannabes, confidantes, pirates, confederates, reprobates, 
miscreants,
escapees, people of no verifiable income, and all card carrying members in 
good standing-
What say ye in regards to waterproofing a (my) sleeping bag?
Pros? Cons?

Background- last fall while up in the big mountains I carried one of those 
emergency mylar bags (space blanket like)
that weighed maybe 4 ounces, and when it got really cold I would use it as 
an outer shell,
but the condensation that formed between the outside of my sleeping bag and 
the inside of the emergency bag was ridiculous.
My bag would be sopping wet, every single time by morning. On a positive 
note, it was way warmer with the emergency bag than without.
I would as a matter of routine, lay up somewhere around high noon and dry 
everything out.

Can I expect my newly waterproofed sleeping bag to act in this same manner 
by trapping condensation inside the bag?
(Removing patrol cap and scratching head...)

NOTE: I originally bought the treatment to use on my tent and fly which is 
still going to happen.

Bag: one each Mountain Hardware synthetic Pinole 20.

sierras.
