If you want to add a protective coating (i.e. Scotchguarding), speak with a professional, since, in some instances, applying such a coating can affect the appearance and/or "nap" of the fabric. Applying such a coating will void the fabric warranty. Should you decide to have a protective coating applied, there are third party companies that offer this service who then offer their own warranty on the fabric. It is important to tell them the composition of the fabric, and is a good idea to test the product in a non-visible spot.
