StopLossBags?

What's the verdict on StopLossBags?  Are they good, bad or indifferent? 

My little 4 oz can of Osmo Polyx-Oil is now half empty, but has skinned over twice.  So I've lost confidence in the remaining contents.  I'm thinking of getting a .5 liter can of the Osmo TopOil next, but I don't want it to go half to waste, too.  So I thought I'd try the StopLossBags.  Just looking at the product I'm a little concerned that the floppy bags won't be so easy to fill with that floppy funnel.  I'm also thinking that decanting a quantity of finish might be messy.  Got any real world experience to share?

I like them. Filling them sometimes requires 3 hands, which I personally find difficult to manage. Make sure you clean out the funnel after use, it’s a pain to clean if any finish dries on it. 

Once finish is in the bag, I found it easy and clean to pour out a small amount. 

At one point the bags would blister up if you put shellac in them. Mine did that, but never leaked. They had offered free replacements for a while if you had that happen, but a couple years later I still have shellac in one and it still hasn’t leaked. Not sure if this still happens or if they warn not to use them for Shellac.

They sell replacement caps for the bags, and I bought a set in case one of mine gummed up but I’ve never had an issue. 

I would have put my polyx in one by now, but I didn’t clean out the funnel well last time I used it and I’ve been avoiding that task.

I have used them and, as stated, they are kind of a pain to fill, but they do what is needed as far as storage is concerned. I have also used ordinary heavy duty freezer bags. Because of the wider opening, you have to use a little more care, but they are certainly cheaper. I fill a bag, close it up, and then put it inside another. I have sometimes cleaned out the original can and put the bags in it for protection and for easier identification.

Either way it helps a lot to have something to hold the bags while you fill them.

I never transferred my little can of Polyx-Oil as it was only 4 oz and that seemed silly to put in a 32 oz bag.  I used Bloxygen instead, but that didn't prevent skinning in my case.

Having it available to me, I once used CO2 instead of Bloxygen and like argon, it is heavier than air and displaces the oxygen. However, every time you open the can to use out of it or to pour into a separate container, the remaining is again exposed to oxygen. I was still losing more than I would have like due to the skimming. Ever since @treeslayerturned me onto these bags, I haven’t lost a drop of finish.

I haven’t. I bought a few packs of them from Woodcraft when they had them on sale and haven’t worried about reusing them. If you use the proper solvent for the finish in the bag to flush them out, then let them dry out, it’ll probably be fine.

Someone a while ago posted about using these instead of stop loss bags.

Sounds like it works just as well and they come in varying sizes.

I've used both. Those work just as well as the Stop Loss except that the spout is smaller and a bit more difficult to work with.
