My trusty rain jacket, having survived well for 6 or so years in all kinds of weather and carrying conditions, has started wetting out and is in need of a reapplication of a durable water repellent (DWR) treatment or replacement. Given the cost of this rain jacket I would like to try and get a few more years out of it. I washed and dried the garment per manufacturer's instructions to reactivate the factory applied DWR, but that did not work.
Revivex application was recommended as a good product for refreshing waterproofing on GoreTex and other fabrics, but I was curious what the collective experience here says about successful (or unsuccessful) product treatments. Anyone have experience with this?
