I thought I’d give a helmet wrap a try with some 2 mil 3M matte black vinyl.
This stuff stretches a lot surprisingly.  It’s pretty obvious that it was not the right material for the wrap as their are many vinyls out there with an air release built-in and can have more stretch on their memory.  Overall effect is pretty good.  I just wanted to cover up the neon pink, which it did, for the most part.

The first piece I applied ended up bunching in a section so I just chopped it.  Lesson learned.
Too much stretch = very thin vinyl.  It’s delicate and chips if hit.
