Waterproofing Nylon Jacket

nikwax DWR applications wont last as long as grangers/reviveX (flurocarbon)

how is the face fabric? … is it rough from use and abuse?

if so it probably isnt worth trying to DWR it …

;)

I would suggest trying thinned silicone adhesive, and try the weight ratio that Richard N. talked about, maybe a little thinner so it’s more breathable. The ratio he came up with and recommends, is for re-waterproofing silicone treated fabrics like silnylon so it may not be ideal for breathability, which is why thinner might be better.

It is inexpensive, and relatively easy to do.  Provides a more long lasting DWR than any of the other ones, only because it’s a much thicker coating than the other ones.  Needs to be occasionally well rinsed, and once in a while, washed and degreased to revive the DWR properties.

If you do try this route, make sure the jacket is very well cleansed and more over, very well rinsed of any residues.  It’s important to pre rinse one’s washer with hot water a couple of times to help with this.
