A month ago after cleaning my engine I tried spraying Armor All on it. It makes it look better than new and touchup is real easy and dirt doesn't stick. After a ride in the rain or long day out with the bugs, just wipes off with ease and then touchup with more Armor All for the next day of riding. I used it on my blacked out engine on my Yamaha Midnight Special years ago, always got lots of compliments on how my bike looked new even after years of abuse.
