Without it, the clear-coat would not cure, resulting in an inferior finish that is prone to damage and imperfections.

Incomplete Curing And Lack Of Hardness

The curing process of clear-coat involves the combination of the clearcoat material and the hardener. The addition of the hardener plays a crucial role in ensuring complete curing and the development of sufficient hardness in the clear coat. However, when clear-coat is applied without the hardener, incomplete curing can occur, leading to a lack of hardness.

Soft Clear-Coat and Vulnerability to Damage

One of the main consequences of incomplete curing and lack of hardness is the formation of a soft clear-coat layer. This softness makes the clear-coat highly vulnerable to damage from various external factors such as scratches, dents, and impacts. Without sufficient hardness, the protective barrier provided by the clear-coat is compromised, leaving the underlying paint exposed to potential damage.

Potential for Premature Aging and Yellowing

In addition to its vulnerability to damage, a clear-coat without proper hardening can also lead to premature aging and yellowing. When exposed to ultraviolet (UV) rays from the sun, the soft clear-coat layer is more susceptible to oxidization and discoloration. This results in an undesirable yellowish appearance that can significantly affect the overall aesthetics of the vehicle.

To prevent such issues, it is crucial to ensure the clear-coat is properly cured with the appropriate hardener. Proper curing not only enhances the hardness and durability of the clear-coat but also provides better protection against physical damage and prevents premature aging and yellowing.

UV rays from sunlight can cause the clear-coat to fade, discolor, and even crack over time. This not only affects the aesthetic appeal of the coated surface but also reduces its overall durability.

Furthermore, without the hardener, the clear-coat becomes more susceptible to oxidation. Oxidation occurs due to exposure to oxygen, leading to the formation of a dull, chalky appearance on the surface. This not only diminishes the shine and luster of the clear-coat but also exposes the underlying layers to potential damage.

Compromised Protection against Harsh Weather Conditions

Another consequence of applying clear-coat without a hardener is the compromised protection it offers against harsh weather conditions. The hardener plays a crucial role in enhancing the structural integrity of the clear-coat, making it more resistant to extreme temperatures, moisture, and other environmental elements.

Without the hardener, the clear-coat’s ability to withstand temperature changes becomes significantly reduced. This could result in cracking, peeling, or flaking of the clear-coat, leaving the underlying surface vulnerable to damage. Additionally, moisture can penetrate the clear-coat more easily, leading to water damage and other issues that can jeopardize the longevity and appearance of the coated surface.

In conclusion, skipping the step of adding a hardener to clear-coat can have detrimental effects on its resistance to environmental factors. The increased susceptibility to UV rays and oxidation, as well as compromised protection against harsh weather conditions, can lead to a diminished aesthetic appeal and reduced lifespan of the clear-coat.
