Extending the Life of Paraglider Fabric
I first heard about using 303 Aerospace Protectant on a paraglider while talking to other paragliderpilots back in 1996, about ultraviolet sunlight damage to our wing fabric. These pilots had used it, so I went to a marine hardware store and bought a couple of bottles.
I applied the 303 Aerospace Protectant to my wing which is a Nova Brand Sphinx, it was new in 1994 the wing had about 300 hours of sunlight on it at that time. 300 hours is the average life span of a paraglider wings fabric. mine was still in very good condition using the normal tests of shear strength, and porosity, and cell stitching integrity.
This wing's fabric is Porcher brand fabric.
I put the liquid on the top surface of the wing following the instructions, allowing it to dry in shade. The top surface is the most susceptible surface to sun damage because it is in direct sunlight while flying. After applying 303, I flew the wing looking for and feeling for any differences in flight characteristics.
