Regarding the February 2012 Chandlery brief on Gill’s aftercare products: The comparison of Atsko Silicone Water-Guard with Gill Reproofing Spray is akin to comparing the performance of a pickup truck with a dual-axle dump truck: They perform similar functions, but they are intended for two different jobs. Atsko Silicone Water-Guard is a very good product for waterproofing lightweight camping and backpacking equipment, but is not intended for use in marine environments as silicone does not provide protection against oil-based stains.
You should have tested Atsko Permanent Water-Guard with the Gill product. Permanent W-G is a water-based fluoropolymer (like the Gill product) that is safe for all washable fabrics, including natural down and synthetic insulated products. It comes in a spray bottle and a 10 oz. aerosol. Both products are compatible with waterproof-breathable or DWR finished products, including semi-permeable membrane laminates like Gore-Tex. The garment dries odor free, resists water, salt and oil borne stains, will not yellow and does not change the hand of the material. Water beading is guaranteed for 25 washes when applied per instructions and washed in Atsko Sport-Wash.
