Cheers for that rich, I just dont understand how the main wrapping company in the U.K. uses them then? Bizzare... I stand corrected if this is true. I can only go on my experience with the wrap that was done for me, which I never had any problems with
I have no experience in doing whole cars, and only worked on small parts, but found that the proper car wrapping vinyls like 3m and hexis were extremely maluable and easy to shape round tough curves, i'd tried using other vinyls that i'd bought in for cutting etc but found they would tear or split wven with heat if you tried to over manipulate them. it maybe avery has a specific automotive wrap vinyl but if they do its a well kept secret as when you search for it not a lot of comes up about it.
both hexis and 3m use air release tech that makes applying the vinyl easier, i've tried doing small wraps which don;t have this built in and they are a pig to get all the air out of.
i think you may find Jay that the place you used were very good at wrapping, hence why yours has gone on well. i've been to a place near me who used 3m stuff and his wrapping had joins all over the place it was very scrappy.
also i think you've taken good care of your car. which in turn has meant the vinyl has been well cared for.
as far as i've seen 3M and Hexis are the market leaders when it comes to vinyl production for auto wraps.
also every wrapper has their prefered methods, materials and tools. same as car detailers.
