I imagine that when you sit in traffic on a day with the sun frying your car, you will feel the difference between s7 and s9 much more.
The sun in NorCal is really intense so I put crystalline on the front windshield even though it’s a lease and did standard 3m ir on the rest. If I owned the car, I would have done full crystalline because the difference is significant.
Btw just for your own peace of mind do a search for reviews from people who went with Rayno and also the installers. My installer was rather upset with them.
I talked to the guy at Spectrum. He seemed nice, but was recovering from back issues and I needed this tint done this week due to hectic next week. Pricing was similar. I would have tried him if I had more time, but then again every time I visit Sunshield Hamid treats me well. He’s been in the business since 1986…
I paid about $1000 (say about cause I got a few other things done) for xpel prime xr plus on a tesla model y. all windows including sunroof and windshield. I’ve seen similar pricing but it was for say pinnacle formula one, or ir. I just wanted to try xpel.
