Snoopy.
Still have not got a camera but this is what I have seen on my car.
(1) Boot - Grommets are painted with overspray and are maroon in colour as are the vibration pads. All surfaces in the boot have been sprayed. No grey or white bits. No running brown sealant. Fine by me.
(2) All exposed curved surfaces are perfectly covered with paint eg 'A' pillar and front wing interface.
(3) Inside front wings below 'A' pillars perfectly painted as are all internal 'B' wing/door panels.
Internal paint finish is excellent.
(4) I have not had the pleasure to look underneath but, for me, what I don't see I don't care about and let it bother me.
(5) There are no grey bits or white bits on the panels anywhere. All surfaces have 'paint'.
I have to admit that I am 100% happy with the finish and fit on my car.
Hope this helps and will enable you to decide on how you will proceed.
