First

This is what I do:
Then buy a touch up stick from vw.
DONT USE THE BRUSH PRIOVIDED - ITS FAR TOO LARGE
Then get some card - an old buisness card will do.
Rip it in half and put a blob of paint from the touch up stick on one half.
Next take a corner of the other half of the card and dip it into the paint and then apply very small amounts of paint to the chip untill the chip is "full" of paint!
job done!
