[BoxsterSteve]

My Arctic Silver Boxster had a few nasty chips, and I went with the Langka system. I've heard that it provided best results on dark paintwork, but decided to give it a try anyway.
Their "blob eliminator" is the part that does the magic, and it took a couple of tries to master the touch to get a good result. The only problem with using too much pressure or speed is the entire touch-up gets pulled out of the chip, and you get to do it again.
I really have to look for the spots I fixed; they blend in that well.
The results aren't perfect, but the car certainly looks a whole lot better now.
Worth the price of admission?
Absolutely.
