Ken,
Looking GOOD !!  
 
Hey Guys,
There are reinforcing rods sewn into the cover that span the cockpit from the dash to rear wall which prevents excessive puddling.
I have left my car out in several good 'ole Southern DOWNPOURS and I mean torrential rain....could hardle see across the parking lot to see the car.   After the storm passed we went out and the cockpit was perfectly dry !  
 
We use marine grade vinyl and it is quite waterproof and the marine-grade has better UV resilience also so the colors do not fade.
Any other questions, please feel free to PM me.  Jim, I am not sure if you were referring to the snapless or your snap cover...but the snapless will not scratch the paint anywhere...
