Tq sir. They only do Tesla.

TSER for heat rejection are usually divided into ratio of 3% UV, 53% IR and 44% VLT.

3M has high IR and UV, so that covered for most 56% of heat rejection portion.
For the VLT portion, having a high 70% visibility means you only block about 14% off the 44% VLT portion with 30% heat still get thru (not accurate but just use for better understanding). Increasing the darkness of the tint aka lower VLT aka 50, 30, 15, etc, will reduce the heat getting thru proportionately.

So if you want minimal heat to get thru, then use dark tints with minimal visibility but for front windscreen, that is quite dangerous or illegal.
So do not expect CR70 or any tints with bright 70% VLT will greatly block heat. What they can do is minimize heat get thru so that your skin won't have those super heat bite/pain or at least feel minimal heat bite when under direct sunlight.

IMO, I don't think Wingard can do any better than the proven 3M CR70 on heat resistance at 70% VLT, so don't expect much unless you lower the VLT further to reduce heat from the VLT portion of TSER.

Even VKool and Irispro metallic based tint that reflect heat WILL still get lots of heat thru at 60-70 VLT. It can't be avoided as the appx 44% of heat comes from how much light you let thru, the brighter the hotter. Just much less hotter than lousy or no tint at all especially with the IR and UV ratio taking care of the remaining half of the heat.

Sure bro pmed yea. Thanks for enquiry 

Hi,can pm for gwm h6 as well,thanks.
