John as most of the modern golf bags use the same type of materials as waterproof jackets etc have you ever tried spraying your bag with Nikwax TX Direct spray?
I use it on my waterproof jackets.

Hi LOS,
Thanks for the heads up on the Nikwax TX Direct spray I've just ordered a 500ml spray bottle I'll give it a go on my golf bag see if it helps repel the water..?, looks good might be just what I'm looking for and it should also come in handy for my Mizuno Impermalite Flex rain jacket I've had it for the past 8 years and I think the water proofing is getting a bit tired & weary, I was going to buy a new one but before I do I'll see if I can save this one first..!.
John
