As I said in my post about Ogio bags, the only complaint I have about my Grom is that it gets completely soaked through when it rains. Because of this, and after reading the GolfMagic Guide to Waterproofing (!!!) I bought a bottle of NikWax Tent & Gear Proof (£5.99 for 500ml). I applied it last Thursday, expecting to get drenched on the course at the weekend to see how good it was but it was a beautiful day on Saturday so didn't get to try it out. It appears to contain silicon and from just splashing some water on once it had fully dried in it seemed to do the job. I'll let you know more once I've been out in the rain though if you're interested.
