wrap tech
Cam,
I have been sticking vinyl on things for 30 years, and there's no way I could ever do the cowl inlets, without a lot of cutting and patching.
I took a 3M wrap course...total waste of time. My opinion is there are definite tricks and tech for areas like this, the rest is practice, failure, practice, failure, ( rinse, repeat).
No doubt the guys at AircraftWraps.com are laughing at us, but fearless guys like you and Bevan are doing pretty darn well by trial 'n error.
One thing you can look at is all the install videos on Vimeo and YouTube, there's nothing like seeing it done. Sadly, most of the pros don't really explain how or why they are doing a certain technique. ( perhaps they want' you to enroll in their $1000 course?
For example, I saw one that showed some white coats in Germany warm & pre-stretch a chunk of vinyl, let cool, then when they applied it to a small car side mirror, the re-heat caused it to shrink back to it's original size, making it much easier to form around the tiny bulbous mirror mount.

you'll see in the comments that another 'pro' says this is totally the wrong way to do it....which is what I really hate about wrapping.
do what works for you, have 'fun', an just thing of all the time and money you are saving sanding -priming and painting.
