You asked about Pure 3X which is supposed to be a "Pure Carnuba" product. I have tried about everything over the years and lucky enough to get a lot of it free to test. I have not tried the 3X because I am totally satisfied with Mothers Pure Liquid Carnuba. I only use a orbital buffer and liquid is much easier to use than paste. I have tried other brands of pure carnuba and some are good but if I have to spend my money for one it is the Mothers Liquid, sometimes bottled as #3 which is part of the #1 thru #3 system they sell that has cleaner (1), glaze/sealer (2) and carnuba (3). I speak of the pure carnuba line of Mothers NOT the cleaner/wax which is OK for the Saturday hand waxer but not on the same level of protection or shine as pure carnuba.
