All the rain wore through the layer of wax on my favorite raincoat. Nikwax spray-on wax proofing is great for a quick fix.
Every summer I lay my jackets out to heat up in the sun and give them a coat of wax. This winter has had enough rain that my favorite jacket started to wick water last night. I was in a bit of a panic as I couldn't find my stand-by coat, but then I remembered I have a bottle of Nikwax in the utility closet.
Nikwax sprays on like water. I used a rag to rub it into the jacket, and the neutral-colored solution disappears into the cloth. Give it 1-2 hours to dry and my coat is waterproof again.
I prefer using Otter Wax because I like the patina the heavier wax gives the jacket. Over time jackets get better and better looking, the more you wax and wear them. Nikwax imbues no patina to the coat, but water beads and rolls off just like you'd used the real thing.
