Hi there,

I was reading an old post and you mentioned that you sell 3m. I just got my car done with 70% crystalline in the rear windows. Factory color was black but no heat rejection. I got the front windows with 20% crystalline. The front ones now look too brown compared to the back windows. The shop offered to remove and reinstall the front windows with 15% 3m Ceramic IR which says it is one step down from the Crystalling but will probably match the rear windows better. I looked at the TSER between the two and they are both around the same. 63% for the 15% Ceramic IR and 64% for the 20% Crystalline. So if TSER is the same, why us Crystalline more expensive?
They also carry 3m Obsidian. I think that is a lowest 3m line that they carry. I've also heard of Color Stable which I think is a lower end but not sure how it compares to the Obsidian and Ceramic IR in terms of color and protection. Crystalline was too brown in the 20%. Fine in the lighter 70%.
