Applying paste carnauba wax
Unlike the paint cleaner and polish, wax is an application only task. A cleaner and polish are applied and worked into the surface to get the desire result. A wax is simply applied to the surface and removed. In practice, this means a minimal amount of pressure is required when using the buffing pad or hand applicator (although some waxes are very hard to apply because of their physical properties).
The key to applying paste carnauba wax well (either by hand or orbital sander) is to have the wax melt on the applicator ready for applying. Take your index finger and quickly move it in a circular motion on the wax. With a good quality wax it should begin to melt in under 5 seconds. This is the consistency needed to apply the wax to the paint.
The melting point of paste waxes does vary, it is easier to melt Pinnacle Paste Glaz than say Mothers California Gold® Carnauba Paste Wax. Hint: if using an orbital sander, place the buffing pad in the wax, turn the sander on at low speed. The moving pad will generate enough heat to melt the wax onto the pad ready for application. You may need to allow the pad to move in a circular motion to spread wax around the pad. This only works where the wax comes in a large tin
The method of applying waxes can vary. Always read the instruction label on a product. For example, Mothers California Gold® Carnauba Paste Wax recommends that the cloth or buffing pad be moist, which is not necessary when using a liquid wax or Pinnacle Paste Glaz. Hint: have a spray bottle with clean water in it and spray the pad or cloth, it is easier than using the tap and gives more control over the level of moistness.
How much wax do I need to do a car?
With a good quality carnauba wax, surprisingly little. Take Mothers California Gold® Carnauba Paste Wax (340 grams) as an example. If applying with an orbital sander, you should be able to wax about 20-25 cars the size of a Subaru Impreza WRX with just one tin. Hint: carnauba wax goes on in a very thin film. With lights it is much easier to see the wax go on. Often the wax is still going when you think the wax is long used, but the lights show otherwise. Most people use too much wax on a car, with experience you will learn that more is not necessarily better. High carnauba content waxes go even further, up to 30-40 cars.
