STONE GUARD COAT
To prevent damage caused by stones, the lower outer body panel (fender, door, etc.) have an additional layer
of Stone Guard Coating over the ED primer coating. When replacing or repairing these panels, apply Stone
Guard coating to the same portions as before. Use a coating which is rust preventive, durable, shock-resistant
and has a long shelf life.
