I try QMI just 2 week ago, I meet their SE at Car Show; he told me their teflon coating can last for 1year++,with only $136. so I try it.
Before Polishing, the shop ask for additional $40 to remove sand at surface. I thought this should be included in the package

after polishing, the shop manager ask me for package of 6 polish for each 3 month! Then I know i get bulb shit
