Key Features of the WB-340 Second Generation Seamless Clear Coat
Stronger Adhesion, No Sanding Required, Just Polish and SprayWB-340 boasts enhanced adhesion, which allows for direct application on previously prepared surfaces without the need for additional sanding. This feature significantly speeds up the repair process, saving time and effort.

Efficient Application, Time and Material SavingThis clear coat not only saves time due to its fast curing and easy application but also reduces material waste, offering a cost-effective and environmentally friendly solution for auto repair shops.
Step-by-Step Application and Performance Comparison
To demonstrate the outstanding performance of WB-340, we performed a side-by-side comparison using two similar car doors to simulate a minor collision repair.
PreparationStart by lightly sanding the car door, applying filler, and sanding again once it dries. After masking the edges, apply a base coat. Once the base coat is dry, use 400-600 grit sandpaper to smooth the surface. Then, use 2000 grit sandpaper with a polishing tool to ensure a smooth surface, ensuring any impurities from the old paint are removed.
Application of WB-340 and Common Clear CoatOne car door was sprayed with WB-340 Seamless Clear Coat, and the other with a common clear coat found in the market. We used the same process on both doors to ensure a fair comparison. One of the key differences during the application is that WB-340 seamlessly blends with the existing paint, achieving a flawless repair.
Baking and PolishingAfter 15 minutes of baking and 10 minutes of cooling, the surfaces were polished. The WB-340 door showed no visible transition marks between the original paint and the new clear coat, whereas the common clear coat had clear visible seams.
Texture ComparisonWhen viewed from the side, the texture of the WB-340-treated surface perfectly matches the original paint, showing no signs of the repair. This is particularly noticeable on vehicles that require an exact texture match, such as German and Japanese models.
Adhesion TestThe adhesion test was conducted by scoring both car doors with a crosshatch pattern using a blade. After applying masking tape and pulling it off, the WB-340-treated surface showed no peeling, while the common clear coat peeled off in some areas, showing the superior adhesion of WB-340.
The WB-340 Second Generation Seamless Clear Coat is a game-changing product in the automotive refinishing industry. Its excellent adhesion, adjustable viscosity, quick curing time, and flawless integration with old paint layers make it the perfect solution for achieving a seamless, high-quality finish in automotive repairs. Whether you’re restoring a minor scratch or performing a full panel repair, WB-340 ensures that your paintwork will be as good as new.
