Frequently Asked Questions
How often should I wax my car?
Every 3-4 months is ideal for traditional wax. Synthetic sealants last 4-6 months, and ceramic coatings can last 1-5 years. If water no longer beads on the surface, it's time to reapply.
How much wax do I need per application?
Typically 2-4 ounces per application for a sedan. A 16 oz container of liquid wax usually provides 4-8 full applications. Paste wax tends to last longer per container than liquid wax.
