I ordered from that website and got the roll of vinyl. Yes applying it requires some effort but not impossible. The effects are very nice from comments that I received. Make a big difference to me as my previous E46 had shadow chrome from day one. So I have to have it this time round as well. And I went for the high gloss instead of the usual matt black. They look the same from far. But High gloss is easier for the eyes to catch imperfections such as bubbes or wrinkles. Matt is more forgiving.
1 roll is enough for 2 cars if you don't make any major mistake.
