Hexis vinyl is really nice, if you look on US forums there are many guys that switched from 3M and refuse to use anything else except Hexis.
They also have a lot of really nice colors, including crocodile skin as well as pearls, gloss and matte finishes. I saw swatches of their vinyl, it's top notch stuff and can pass for paint.
I agree that using cheap vinyl is absurd when you consider the labor involved, and that you basically need a full roll for most vehicles to do a nice job and minimize seams.
So I'm guessing the cost adds up as follows:
Hexis 54" x 65 feet of satin white is about $900 CAD shipped (Status Motors out west sells this if you want to verify) .
Approx. $100 is needed for supplies and wear and tear of equipment (digital heat gun, usage of magnets, etc.)
So that's $1000 in materials to do an external wrap on an average car.
I saw the 3M guys at SEMA perform a multi-layer (3 different vinyls) wrap on a whole car in 5 hours with a crew of 3 guys, so 15 hours for them total.... Either way, these guys are real pros doing this every day, so I'll assume a shop here with 2 guys doing a single layer vinyl would take 12 hours. At $65/hr (which is a fair shop rate considering cost of renting, hydro, and such) each that's $1560 in labor.
Total about $2500....
Is that basically it?
