I'm having a bear of a time with Langka trying to repair chips on metallic paint (08 steel silver). While the product/system does exactly what it says and works beautifully, what it seems to do with metallic paint is remove the metal flake (which I assume rises to the top as it dries) leaving a lighter, non-metallic color in the chip. The good thing is you can remove all the paint from your chip and start again fresh.
I have not tried their "squeegie method" suggested on their site yet, but I fear I will have similar results when I do...
