You tried it yourself? Good quality wrap is very very easy to work with once you get a bit of heat into it 
Honestly, I have no idea what I'm doing. If you said to me that it needs to be applied naked, in the sun, wearing a cap sideways, with a tub of vasoline I'd believe you.

Funnily enough I hear that gives good results!
On a serious note, buy a 99p a4 sheet from eBay & practice. Clean the surface, remove the backing paper & apply. Get a heatgun or hair dryer and heat up the vinyl, it'll become pliable & stretchy so you can shape it over whatever it is your wrapping.
If it's not right, reheat it & it will return to normal so you can try again as many times as necessary. You'd have to be a complete retard to get it wrong!
