Review on Color Changing Deionization Resin for Aquatic Life Mixed Bed by Christie Cox

I use it to wash expensive cars. It really is the only way to wash a black truck and not worry about water stains. I've noticed several people complaining about a hole in the Mylar bag. What these people didn't mention is that the resin was sealed in 5 other bags inside this bag. I personally haven't seen any other place that took the time to do this. As for the durability of the product. This is probably the best resin, or at least as good as any top brand resin you will buy. I've washed my very large truck and SUV several times (full wash) and still can't get tds without a pre-filter. In terms of quality and quantity, this is good business for me.
