i just chrome stripped my doors and as i had a bit left over i put it on the roof rack strips on the roof just to see what it would look like...while doing this a tree also got some chrome strip on it lol...
anyway IMO it looks silly...
y would you wanna draw attention to 2 lines on your roof??
thats just what i think but id try it out first like i did while i was mucking around to see if you really like it first - you could even use al- foil
