I had rubber (EPDM) on my last trailer and had trouble with it shrinking and being dirty looking. Before I sold it I re-caulked the front and rear seams and had to make about a 4" wide bead of caulk. Wish I had known about Eternabond back then...
Oh - no spider web cracks on mine and it has been stored outside in Colorado all its life.
