Carnauba Wax
Natural wax from carnauba palm leaves, prized for its deep, wet-look shine and warm glow. Offers excellent water beading but lasts only 4-8 weeks. Best for show cars and enthusiasts who enjoy frequent waxing.
Check priceSynthetic Wax (Polymer Sealant)
Man-made polymer sealants that bond to paint, providing slick finish and long-lasting protection (6-12 months). Easier to apply and remove, but may lack the deep warmth of carnauba. Ideal for daily drivers and low-maintenance owners.

Quick questions
Can I apply carnauba wax over synthetic wax?
Yes, but it is not recommended. Synthetic sealants create a slick surface that prevents carnauba from bonding properly. For best results, apply carnauba over a clean, bare paint surface or use a hybrid product that combines both.
Which wax lasts longer in hot climates?
Synthetic wax (polymer sealant) lasts longer in hot climates because it resists UV degradation and high temperatures better than natural carnauba. Carnauba can melt or degrade quickly under intense sun, while synthetics maintain their protection for months.
Does synthetic wax damage paint like some abrasives?
No, synthetic waxes are non-abrasive and safe for clear coats. They are purely protective sealants. However, always follow the manufacturer's instructions and avoid applying on extremely hot surfaces or in direct sunlight.
