@ Dr MUDHAN :
Nice to Know that you enjoyed looking at my polo. Ofcourse i dont do as much research as you but just a little. have a lot to learn from you.
About the roof wrap i have installed the carbon fibre vinyl.
Before putting this one i did enquire at few places including 3M. 3M was the costliest and the one i put was a decent one. i did not find any difference in the quality of sticker used by 3M and the one that i have installed.
3M gave me a quote of 11.5 k
and i got it done for 2.3 K
from my guy. There were quiet a few types available but opted for this. in fact if i would have installed the dull black it would have been done for 1.5 K.
The only drawback is that the dust settled on the car is now very easily visible on the roof.
Other than that i did not find any problem with it. There might be some difference in the quality of 3M and this which was not visible to my naked eye but still i felt that in that amount i can change the top of the vehicle 4 times at the interval of 6 months in case if there is fade in colour. Even 3M was giving a warranty of 6 months only.
