I know this is an old thread but here is the report so far. I bought the 18 inch wide roll. I used it this last weekend to head to Woodward Dream Cruise.
1 18 inches is to wide for the front of a Mustang (would work great on front end of a car trailer.
2 Did not conform to the front end very well looked like crap
3 It did it's job kept the bugs and rock chips away
4 Came off easy did not bother the stripes
5 Left a residue on the paint (I think this was cause by it not conforming well)
6 Cleaned off easy except for one spot that looks like a rub spot on the paint I will polish it tonight to see how hard it is to clean off and what is the best way to remove it.
7 I am going to cut the roll using a razor blade into 3 inch wide rolls to see if I can make it fit and conform better will report back then
