Had my OEM V-Kool tint done sa tinthub ortigas. Cost me 5.8k for a 2k6 santa fe. Mabait sila at accommodating. Sagot lahat ng tanong ko. OEM 5 for sides and rear with OEM 20 for the front. The tint is reflective dark grey with the OEM 20 being a lighter shade of grey from the outside. Ok during the day yet madilim sa gabi yung OEM 5. The 20 is a better bet for people na hirap sa gabi mag drive dahil sa tint, ideal compromise ito. Pulido naman pag-gawa nila, si dimples ang nag tangal/kabit ng tint. I even bought a bottle of watermarks remover para luminaw yung salamin at makita ko yung difference.

*FYI... My garmin GPS on the dash can't lock in sa sats anymore (from 3 out of 5 bar before, now 1 or none) yet my phone can pick up sats under similar conditions on the dashboard...
