i need some tips/ advice on how to use touch up paint to get a good smooth looking result. i went to pep boys and got the pen 2 in 1 min gray touch up and used it on 2 little chip spots, and the color is perfect but it dosent look smooth at all, you can still notice the spots pretty easily. also, how do u use it for small scratches, cause the way the chips came out im not gonna try to paint over any scratches.. it looks like crap
