I bought 5'x5' of Silver Chrome Wrap to wrap five parts on my Honda Metropolitan scooter. While these parts are more curved than the average car, all but one of the panels we attempted to wrap are reasonably flat.
After playing with the vinyl wrap for the course of a day, we had exhausted all options and ended up painting the scooter instead of wrapping it. The chrome wrap just DID NOT have the stretch or flexibility that was necessary. We used all of the tricks in the book, from cold stretching (not really possibly at all with this wrap) to the heat gun. After failing profusely a few times, we cut a piece off to experiment and found that no amount of applied heat would help make it stretch, and it couldn't shrink enough to do us any good either.
The flatter areas came out amazingly well, which just made us more frustrated as we could see the potential this wrap has, but it just wasn't malleable enough to do much of anything.
This wrap would be awesome for flat or 2-dimensional curved surfaces, but please don't go through the heartbreak and try to apply it to anything with real shape. The wrap just doesn't have the stretch or malleability to do it.
The attached image is our best attempt before removing the wrap and prepping to paint instead. This small panel's sorry state took us nearly 2 hours to accomplish. I'm telling you, this wrap doesn't behave like it should.
