VKOOL Elite - As cool as day 1 since 2002 tho has since shown some metal discoloration.
Huper Optik C40 - As cool as day 1. Sold car after 2 years still rockin'.
Huper Optik C30 - 2 months old. Still testing. Been happy so far.
2002 to 2013 and the Vkool Elite tinted vehicle is still cool since day 1. Impressive. It is surprising that we do not share the same experience. To clarify, the Vkool tinted vehicle, after 3 years is still cool but not as cool as since it was tinted since day 1. A *slight* loss in efficiency. My vehicle was tinted with Full V-kool package and I believe the front windscreen comes with Vkool Elite as well. Not too sure about the side and rear windscreen(didn't inquire since the package came with the vehicle). I have kept the vehicle for less than 6 years, so didn't notice any metal discoloration.
Your vehicle that was tinted with V-kool Elite, is it on the front windscreen only or on all front/sides/back? If the V-kool Elite is only on the front, what's on the sides and rear?
Any comments on which vehicle is cooler, the one which is on Vkool Elite or the one with Huper Optik C40? Or there is almost no difference between the two? Similarly, the vehicle that was on Huper Optik C40, is it on all front/sides/back?
FWIW I checked the specs of the Huper Optik C40 and V-Kool 55. The Huper Optik C40's TSER is 55% which is lower than V-Kool 55's TSER at 58%. To top if off, the VLT of the V-kool 55 at 58% is higher than the C40's VLT at 42%. In other words, the Vkool 55 is not as dark as Huper Optik C40(more JPJ-friendly) and yet provides higher solar energy/heat rejection. The spec of the V-kool 55 seems to be better than Huper Optik C40.
After looking at the specs, I may be considering the V-kool Elite/55 and Huper Optik Sech60/C40. Price-wise will be close. Just a matter of performance and durability. I believe both are smart tag friendly, though in my experience the V-kool is not auto-gate friendly, as I have to wind down my windscreen to open the front automatic gate of my house. Not too sure about the Huper Optik.
C30 is too dark for me, personally.
I would appreciate your response on the above. Thanks.
