I have used the pens several times and have never cared much for them and the color has never been just right. This last go around i got a local body shop to mix some paint and and put it in a paint sprayer bladder. It has worked better than any other touch up i have used. They mixed clear in with it and its thinner so you can do a better job. They also supplied these very handy applicators. I would best describe them as plastic tooth pics with soft brissels on the end that form a circular shape. Im sure its a typical body shop supply.
