Carnauba Wax vs Gelcoat Polish/ Sealant which is better?
No one debates the need to seal and protect gelcoat finishes but there is disagreement over how best to do it. Many "old timers" will only use a natural carnauba automotive wax but boat manufacturers are increasingly recommending only gelcoat sealants. There are a number of valid reasons for this. The durability of carnauba wax is limited especially on power boats. Combining the corrosive environmental effects and the abrasion caused by the hull cutting through the water limits carnauba wax durability to 60 days or less. Above the water line carnauba waxes start to melt around 150 degrees, direct and reflected UV and thermal radiation is literally melting the wax off the finish.
The synthetic sealants used by GELCOAT SHINE have better bonding characteristics than carnauba waxes, better abrasion resistance and melting points in the thousands of degrees. Synthetic sealants WILL outlast carnauba waxes and produce a brighter shine. Sealants should last 180 days.
Another problem has to do with the very nature of gelcoats. Gelcoats are porous. Seen under a microscope, your boat's flat smooth gelcoat surface has millions of tiny holes. These holes, or pores, fill with microscopic grime and marine scum which promote oxidation. Think of this as "plastic rust" eating away the gelcoat from the inside.
Having GELCOAT SHINE apply a "protective" gelcoat sealant will greatly retard the oxidation process and add years to the life of your boat's gelcoat finish.
