[pct-l] To waterproof or not to waterproof (ye old sleeping bag)

[Heather Darnell]

Paint, I used the emergency mylar bag with my hammock. (Long story short, too small a pack, too much food = no room for sleeping quilt!)
After basting all Friday night, in 30-degree weather, I opened a slit in the end for Saturday night, again 30 degrees. Slid the whole contraption over the hammock. The ventilation was a huge improvement. I have repeated this since and as long as my skin doesn't have to touch the mylar I'm okay! (Love my silk jammies!)

If you have already done your bag, you could consider inside-out, as though you were using the VBL? 
Or, if you haven't, perhaps just either top side and edges only, if you cowboy camp (shelter-less) or bottom side and edges, a' la "bathtub-floor bag", if you camp footprint-less?
Just bandying about various thoughts, not saying they are good ones...

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.

Wanna? hijack the thread?
Wanna? talk about last night, hmmm?
Something else a little more riveting?

Go for it!
