Our 70 pound Curly Coated Retriever spends a lot of time in our boat. We added HydroTurf to the passenger floor specifically for her, so she doesn't keep slipping around when we make sharp turns and such. We don't trim nor file her nails in the summertime (they wear naturally on our beach) but there is absolutely no damage to the HydroTurf at all.
Install it and get on with your life... HydroTurf is the best.
There were two reasons I pulled up the Hydroturf on the 96 GSX I've been working on:
1. I HATE purple. Changed to black.
2. The rear mat had been shredded by a cat that was sharpening its claws at night on the moored ski on a regular basis.
