Good, Color beware
The water repellant spray works great and the brush works well, however it would be nice to have a stiffer brush for use with the cleaning spray. The cleaning spray works wonders, I was dinning and somebody at my table spilt some red wine that got on my hat and after two treatments you can hardly tell where it happened. I would also be careful with it though, I have a grey hat and you can see a bit of white left after using the cleaning so I imagine if you had any darker a color that'd be very hard to remove.  That being said, with enough elbow grease and the brush I can almost completely eliminate that.
