This wax produces such a brilliant shine, and protects your paint from the elements. I bought a tin of this wax 2 or 3 years ago, and have only used a quarter of a tin! I tend to wax every other month, which it makes it very economical. The results are long lasting, and you would be fine giving your car a coat twice a year. Rain will simply run off your car, and tree sap/bird droppings will not have a chance of damaging your paint. If you have a look on Youtube at the results of waxing with this product, you will have a good idea of what to expect. I'd never use any other wax! For best results give your car a very good clean with car shampoo and a mitt, then follow with a pure polish, and finally finish with Meguiar's 16 mirror glaze.
