Hi Folks. Well, after many years of service, my old Barbour needs a reproofing. Unable to find a Barbour stockist here in KC, I bought some Filson's proofing wax. Several questions: 1. Is the Filson's OK for my Barbour? 2. How do I reproof it exactly? I can turn this nice English hunting jacket into junk in a second. Any ideas on how to maintain it well? Thanks!
