I have a small (1/4") scratch on the bottom portion of the side skirts or whatever you wanna call them. It's hardly noticeable and on the bottom when you really have to look hard to find. I got this one from my local dealer but it's like a nail polish brush and a crappy ball point.
The guy in the shop said to use a toothpick instead of the brush but that didn't work. I wiped it off fast right after I applied it. Maybe I'll get the one you have.
