Just a note about silicone coating nylon.
If you watch that video you will note that the first type of silicone did not work.
That is the same reason why some fail at seam sealing their shelter (silicone peeling/rubbing off) . Because they start with the wrong silicone...
The second type the guy used (GE II 100% silicone) is the correct type.
Any translucent 100% silicone will do, BUT NOT the other stuff.
BTW, you could just rub the mix on with a sponge. Probably more likely to get an even coating.
