Permanent Water Guard

> e Atsko Permanent Water Guard DWR?
Reviewed at backpackgeartest.org in a full Test. Very good stuff, works well, sticks well. Fluoropolymer. But use the Atsko Sports Wash with it. I think this is mentioned in the reports.

> f Scotchgard Outdoor DWR
I believe this is silicone. All silicones rub of fairly easily.

> whether silicone based DWR is good for waterproof/breathable fabrics
Not a simple question.
IF the W/B fabric has a fluoropolymer DWR coating, and most of them do, then the silicone treatment will NOT stick to it. It will rub off, or wash off, very quickly. Failure.
But once you have used a silicone spray on something, fluoropolymer sprays won't stick either.
So you can really stuff things up by using the wrong spray!
