The package did not arrive
I was sceptic at first, but gave a chance to this thingo as it was far cheaper than the local paint shop's price. It's a substance of magic, works as seen on video. :) Package arrived in 10 days from PL regardless of Christmas holiday, well packed, no missing part. After gringing the plastic surface with wet 600, 1000, 1500 and 2000 papers I applied the liquid as instructed. It took only an hour to finish with both sides, result looks very nice. With the provided amount of liquid I would say one can renew about 10-15 pairs of headlights. I am really curious on how long the result will last. (I decided to apply a clear wrap film too as it comes for peanut.)
