Rating : - Nikwax Wash-in. It's always good to read the instructions and...
Follow them! I've been using these exact products for a number of years. I use them on my Aerostitch and other riding gear. In fact I was in a downpour in Northern Montana on Thursday en route to the International BMW Rally in Gillette, WY. I stayed dry! Using more of the product than is directed can be self defeating.
"Nikwax" Most excelent!
