Yeah, you have to get the roof clean. Once you get the streaks off, the WashWaxAll will help with the streaks. We only have streaks where the decal points down the front of the 303.

Thanks for all the great replies and tips. So, several have said to get the roof clean...are the streaks being caused by the roof? What is the best way to clean the roof? Sorry for all the newbie questions...this is our first camper and we have had it less than a year now.
