I did tint on all the glasses of my new house before installing the iron grille.

My friend gave me a really Good price, it was an OEM tint from US with very high heat rejection and dark colour. With installation, rm10/sqft.

He does provides me the option of Korea tint with similar heat rejection spec but Korea tint might have quality issue where the colour might fade unevenly towards the time where the US tint will just fade in colour consistently.

Happy with his installation and quality of work. Somehow I doubt he could help many of us as his shop is in Ipoh
