What does everyone use to reproof there rugs. I had mine professional washed and reproofed this year. With the persistent rain the last two day I put my hand under chunkys rug and it was soaked right through. Once they loose there waterproofness what do people use to make them waterproof again. Ive normally used the nikwax and put the rug in a bucket overnight. It wasn't always 100% but to have had it professionally done and it be soaked right through its very disappointing.
