This will help ensure that the protector is compatible with the cover’s material and will not cause damage or discoloration.
  • Follow the Manufacturer’s Guidelines: Finally, always follow the manufacturer’s guidelines when selecting a protectant for your tonneau cover. Different ones may require different types of protectants, and using the wrong product can cause damage or void any warranty on it.
