Because the problem seems to resemble holograms, I would think that your finishing step is what needs to be tweaked. Your
Menzerna Super Finish PO 106 FA should be finishing beautifully, but you could step down to a softer pad than LC White (a
polishing pad). Try one more time with a Gray/Blue LC pad (finishing/no-cut pads respectively) and work it until it is all but gone (at
least until it flashes clear but stop before the thin film of polish is gone completely).
I've had great success with
Pinnacle XMT 360 and
Poorboys World Polish with Sealant with a DA, and of course
3M Ultrafine via Rotary when battling a soft paint that wont finish flawlessly. The way I see it, if the polishing you have already done did not remove the defect, it's either a problem "in" the paint (how sure are you,
really, that its factory paint?) or it's polish induced marring and just needs to be finessed out.
Just my thoughts... :dblthumb2:
Edit: Oops, you only have LC Orange and White... so much for my softer pad idea for now.
