My 6 is painted by HOR. The wifes 6 is OEM black. Neither one has a 'miles deep clear coat' look, so IMHO, the 2 paint jobs are ~pretty similar~.
Considering that paint, a center-stand, clear t-sigs, front fender extension (now removed), and a Baggershield added 2 k to the price,,,, eh,,, Now I can say it was not a MUST HAVE due to any shortcoming on the OEM paint. A different than OEM color is 'nice',,,,
If ya want a something to 'Polish and Admire/Pose' with, well, there are far 'shinier' paint jobs / far shinier bikes to be had.
