Review on Ultimate Protection: Heavy Duty 6x6 Ft Camping Tarp with Carrying Case by Tim Morrison

is not waterproof. Used that in the back seat for a pup who pees while driving (totally different problem). She peed on the tarp and by the time we got to our destination in less than 10 minutes the tarp had already started to seep. I had puppy pads under a tarp suspecting it wouldn't be waterproof and I'm grateful I kept the seats in my new car. I'm sure I could use this for other purposes, but absolutely don't trust it to prevent water (or urine) damage.
