I have had only moderately good results with it. It is a petroleum distillate that softens partially cured touch-up paint, which then allows you to "shave" off the extraneous paint from around the chip by rubbing it with a hard flat surface covered with a finely woven cloth.
The problem I have experienced with it is that it seems to discolor the touch-up paint that is left behind in the chip, and you never can actually get the paint in the chip to fill up to exactly the right height. I am still trying to figure out if this product can really work as good as they say it does. I have been experimenting with cure times and rubbing methods.
I don't think that Langka would fix the chips below the gas tank door; they are on a curved surface...but a non-metallic paint like white probably has the best chance to work.
I too tried Langka and frankly wasn't impressed at all. When I tried to use it on the Sapphire color it seemed to darken the touchup paint and you could REALLY tell where it had been touched up...not impressed at all. Now maybe I am not using it right but certainly not impressed.
