I don't think that plastic will accept dye. If they are the bindings that I am thinking of, they are painted white. The only bindings that can be dyed are Markers. I dyed my griffin heels black, it does make it difficult to see the din numbers. As far as damage to the bindings, I doubt it will do anything. Being submerged in water is not an issue for bindings, and the dye won't so anything corrosive. You rinse in cold water anyway.
