Their N. American headquarters is here in Seattle and I know a guy. I asked him after I posted this and he said TX-Direct would help, but their tent spray would work better. I don't remember which I used, but it worked pretty well. Probably time for a new coat, it's been a few years.
I use various Nikwax products on jackets and fleece and other outdoor wear. It's really wet here for most of the year it's a great set of products. Only did the bass bag once, but it worked out great.
If my post starts sounding like a rant, please start again from the top and imagine John Malkovich as the narrator. www.troyonbass.com
