I have a shell/jacket that I have worn for 20 years. I love the style and cannot let it go. It was a nice water repellent material when I first bought it but with years of use, it is really soft and absorbent now. I have had people suggest using a weather proofing product etc. but I have never met someone who has actually restored a water proof/ water repellent item. I found this stuff and have considered using it but I fear I would end up with a sticky mess. Spray-on waterproofing for soft-shell clothing Has anyone restored a jacket, tent or something using a spray on product? I have also seen a product that you spray then iron or heat in the dryer. Do the ones that you heat work better? I can post a picture of the jacket later, if needed.
