anyone know what's in the stuff?
303 Fabric Protectant seems to be a well-guarded secret. West Marine has duplicated the 303 Vinyl Protectant with pretty good results but they don't have a similar product for fabric.
There are some alternative products - like Aqua Tite - Sail-Rite carries it
Sunbrella Fabrics, Sailcloth, Canvas and Sail Hardware, Gill Foul Weather Gear and More!
