Acrylic gesso, at least the brands I tried, does crack if rolled up 
repeatedly, and that risk augments with changes of temperature, especially 
exposure to cold (gets brittle in the cold).
The brands I tried were: Liquitex, Stevenson, and a few cheaper house 
brands.

Thanks Paul for the suggestion of the "sun block" fabric. The support does 
make a huge difference, and we sometimes overlook that factor, trying in 
vain to compensate with paints and exotic methods.

I think rolling larger instead of too tightly would help prevent crack 
damage. Putting the roll inside a rigid tube (cardboard or PVC or ABS) could 
help prevent edge bumps and other mishaps during travel and handling.
