The key to Langka is to let the touch up dry enough...Like at least an hour, but 3 is better...the directions say it must be dry to touch...At least! See it as a tool....For the right kind of chip, like where there is a clear crater though the color coat into the primary, langka works great...I had one on my hood a couple wks ago where a rock did its job form a truck wheel. Knowing I would try Lankga on this, I blobbed on the touchup, not minding that it was outside the borders of the chip...I let it dry a few hours, then took the plastic card and wrapped a single layer of non-fuzzy cotton around it tightly..you dont want to be removing paint from within the crater. Then, just rub over the area, but not IN the area, and youll find the paint has come off, except within the crater...I couldnt even see it afterward...Then, I just applied a little hand buffing with your favorite polish/glaze, and a coat of wax over the area, and it was done...perfect.
