There are a variety of Protect all products. If you are referring to the Protect all Quick and Easy Wash then you should be just fine. It will work like the other dry wash products. My personal belief is that you don't have a protected finish like you would have if you wash and waxed your coach but it will give you a clean look until you can get a proper wash and your bi-annual wax job. Water is your friend when washing your coach but those selling this stuff are likely to start flaming me any second. I tried it and it does work. I just don't think it's a good long term option compared to washing your coach with soap and water.
