Spent 4 hours today cleaning every little spec of dirt off the Banana Boat and the trailer. Some spots weren't coming off so I flipped to the other side of the worn out sponge that had more of a rough backing to it. Didn't realize it in the bright sun but I scratched up the coat in the places I rubbed pretty hard. It's not noticable unless you really look at it but I know it's there. I am so stupid sometimes. Bummed....
