After many years on my gear, (riding textiles/bags, paddling gear, & aviation equip) fading, cracking, and crazing are things of the past. Colors stay fast and fabrics always appear as new without the lubricity of Armour-All. Nylon straps will outlive your mother-in-law. Items with reflectivity are renewed and protected also. Great on directional lenses and all plastics as well. Turns black black again and keeps it that way. It's really just one of those products that delivers what it offers. Even safe to hit the skin with it if you're caught in the rays. Very high SPF. Wouldn't be without 303. Cheapest by the gallon, but you'd have to have the gear to justify that.
