  7. Sand the surface (optional): If desired, lightly sand the dried clear coat with fine-grit sandpaper to ensure a smooth finish.
  8. Apply additional coats (optional): Depending on the desired level of protection, you can apply multiple thin coats of the clear coat, allowing proper drying time between each coat.
  9. Final curing time: It is essential to wait for the clear coat to fully cure, which can take several days or even weeks, depending on the specific product.
