I managed to get a trial roll of the Crystalline a couple months back. I found it to be a very nice product. Stretches well without cracking and it is water-resistant.
I tested a couple of samples printed on my Canon 6100 and found that if you wait 24 hours after printing, you can spill water on it and blot it up with zero damage.
On the other hand, when I rubbed the area while damp there was a small loss of pigment.
When I originally ordered the sample the BC salesman told me that if I wanted a true water-proof finish I would have to overcoat the surface with the Timeless.
I think though for most applications it should be good without the extra coat.
