The adjacent picture of the Mother's California Gold Instant Detailer is one of those products that can be easily applied to the paint of your vehicle after it has been washed.
Typically, application is done in sections i.e. quarter panel and wipe on with a clean microfiber. Working your way around the vehicle and using a clean and dry portion of the microfiber it should take no more than 10 minutes to complete.
Ideally you can apply a quick detailer product (such as the Mother's Instant Detailer) once a month. Each application enhances the current paint protection barrier between the paint and elements,, in turn helping extend overall longevity.
