Regarding the February 2012 Chandlery brief on Gill’s aftercare products: The comparison of Atsko Silicone Water-Guard with Gill Re-proofing 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 very good for waterproofing 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 instead. It is a water-based fluoropolymer (like the Gill product) that is safe for all washable fabrics. It is fully compatible with waterproof-breathable or DWR finished products. The garment dries odor free, resists water, salt and oil borne stains, will not yellow, and does not change the hand of the material.
