If you don’t have a patch or two on your barbour, you haven’t broken it in yet. I’ve had entire sleeves replaced on some. Sending it in for reward is the same option.
From what I've read the hair dryer is an important step in getting the wax to settle on/in the jacket's shell and to get rid of the stickyness of fresh wax.I watched Muffy’s video and followed her technique. It turned out very well. Just don’t over wax, but if you do blend it in with the hair drier.
You should hang the coat for a couple of days and can even touch it up or blend the wax in with the hair drier in that time.
The coat remains waxy for about a week. I take if off before I sit in the car. It did have an aroma for about a week but is fine now.
