Same formula, same thing.
Aerospace 303 has a "Fabric Guard" version, but I've only noticed that it is a thinner viscosity and this may have something to do with requiring a deeper penetration of the formula into the weave of the fabric and a quicker (six hour) drying time. I use the original Aerospace 303 on everything, including fabrics, and it repels dirt, waterproofs deep into the stitching, and water beads up on it. It just takes a little longer to cure so I usually wait eight hours or so for it to dry completely.

I bought their spray marketed for fabrics and their wipes marketed for plastics, but they could well be the same compound.

I also have the original 303 product and it works great. I like using it since it is not greasy/oily.
