TW Ice simply will not last - proven fact. If your car's finish is in very good shape to begin with then Ice will make it look great. For a short while. If your finish needs some real help, it simply does nothing to correct issues. That doesn't make it a bad product, don't get me wrong. It just won't correct defects (swirls, etching, etc) and it doesn't last. It also doesn't really offer any protection since it's a pure polish, not a wax/sealant.
