Water Proofing / Replellent For New Bag

[leaky5]

I have nearly finished this bag and would like to water proof it a bit, its unlikely to go out in major down pours, but is likely to see rain at some time.

So far it has only had a few coats on Neatsfoot oil. I normally just use Kiwi shoe polish on my knife sheathes, rifle slings etc. Once soaked in and buffed up it does not normally leave a tacky finish.

So I could just use netural Kiwi and maybe even Leder Gris clear, which I think may give a more waterproof finish. Has anyone ever used Leder Gris or can recommend anything else ?

Fiebings has a product named bag kote which is pretty much what you're looking for.
