Take your time using very small dots of touch up paint and you can get good results. The very fine tip on the paint pen allows you to do this. Squeeze too hard, though and you’ll be wiping off the “snot nose “ globs and starting again. This isn’t a brush-style applicator, so don’t think in terms of smoothing out the applied paint. Instead let the small dots fill in the chipped area. This can take three or four layers to accomplish, so allow each layer to dry and then apply lightly again.
