Have used Sno Seal https://www.paddypallin.com.au/sno-seal.html. It is okay, albeit quite thick and can be sticky. It is best applied by first heating the tube in hot water, making it runny, and hence making it is easier to put on a thin coat.
I still prefer the Hestra goop, but it is starting to get ridiculously expensive in Australia. An alternative might be something from Nikwax range.
Be aware that mice love the Free the Powder glove balm. It does smell good. I've had a mouse chew through an outer nylon bag, (Sync), a helmet bag, (Smith), then a zip lock to get at the stuff. I guess I had a small cloth in the ziplock with balm on it plus the container.
Keep in mind they're now saying it's best for only 1 year. So do use it or lose it. I cracked open my jar, and it's definitely a lot more dried out then last season. I may mix in some liquid leather conditioner in it to see if that loosens it up.
I think you can take this to mean that the treatment will only last at most 1 season even if gloves are just sitting on the shelf.
