I tried it, didn't like it, and it didn't work well. I do believe I followed the directions adequately. I tried it more than once.

I've had mixed success with Langka, it did not work at all well when trying to touch up a chip on my Silverstone S2000 - it seemed to discolour the touch up paint leaving it a darker shade than when applied In my opinion it will work best on dark and solid colours, red and black ought to be fine. I actually lent mine to Andy_Pandy to help him repair a scratch on his black S2000 and he felt it helped give a better finish than without using it.

IMO it isn't a magic solution but it is pretty easy to use. If you are a perfectionist I'd save your money towards a respray - that's what I ended up doing with my front bumper

I agree. I used it on my silverstone (bumper nick) and it was visibly darker.

I also used it on my sons black Civic and it worked much better (still not as good as they would lead you to believe).

I've used it on a few cars before. It works pretty well, better than touch up paint alone. However, technique is very important, especially the wiping off part. First, make sure the touch up paint is actually dry. Try to find some really high stitch count cotton, really smooth stuff. When wiping (drying) off, be sure to stop before it's level, and switch to a dry portion of cloth. ALWAYS use a backing card or else it'll take off too much paint.
