If scratched, the color coat of paint does nick/scuff and these marks cannot be rubbed out.
If polished, the finish will become less matte and more glossy over time.
How to Clean
For light deposits: Use Harley-Davidson Denim Paint Cleaner and a Softcloth. This helps remove finger prints and light soil.
For heavier deposits: Use H-D Sunwash and a clean Wash Mitt. Rinse thoroughly with clean water.
