I have a Carefree of Colorado bag awning on the Pup. It's made out of a thin plastic-vinyl type of material. I'm sure that this is common to most bag awnings, but the top portion of the bag where it attaches to the pup, is actually the first 4-6 inches of awning. It's hard to explain/describe, but I think you all know what I'm talking about. That top portion of the bag is being effected by UV (I suppose) and is becoming brittle, for lack of a better term. I noticed at the end of last season that it is starting to have multiple cracks along the full length of the bag. Is there something that I can put on that vinyl to restore its flexibility so it doesn't crack worse? Can I wipe a liquid on there, or paint a thicker film of something on it? Any suggestions. The awning is about 5 years old. I'm surprised that it's in that kind of shape, the original one was about 10-11 years old and was in better shape than this one is.
