Nikwax Care Kit for Waterproof/Breathable Fabrics

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!

I read up on all the various waterproofing products because my cloth (600 Denier Carbolex) motorcycle jacket needed to be treated. So I decided on Nikwax. I bought the pre-wash and the spray on waterproofing, since the wash-in waterproofing would waterproof the inside, which wasn't needed. With the spray I could get it on the outer shell where I wanted it. I followed the instructions, first wash the garment then spray and let dry. Then I wore it in the rain a few weeks later. I got soaked. It actually made it worse than before. I wish I had just left it alone. I've used the inexpensive spray-on products that work better than this product. Save your money.
