Fair point.
The shop you/us are hiring makes a huge difference.
For my yellow Huracan i hired Detailing Dynsmics out of NY, they did a fantastic job wrapping all the sharp edges. Me happy. Btw, they did Lamborghini Veneno.
With my AGT-P i went to a local guy doing only a front, hood, sides. Mediocre job to say the least.
So, you are right, every shop differs.
But, the guy makes some very valid points, wouldn't you agree?
