I've got a few chips along the side of my Zed after some road debris flew up and hit it ...
I got the touch up paint from Nissan and the colour match was spot on ...
Someone on the forum advised me to use a toothpick to apply the touch up paint ... one dot at a time, doing it very carefully ..
It takes longer to do but I found it to be a very good way to avoid getting paint on the surrounding areas ...
