Ok, I know I have been whinging about the heat coming through the glass roof of my model 3 a number of times on this forum now, but I am determined to minimise the problem as much as possible. ALiExpress sunshades do blockout some light, which is not my primary concern, but doesn't seem to do much about the heat, and the rear one impedes the vision somewhat. They also completely defeat the purpose of having a glass roof. I had called a number of window tinting places, so far no one wanted to touch the roof. Some are not even keen to do the rear roof, as it is a large piece of glass and therefore difficult to do. One place will do the rear glass, but only with the thinner and lower heat rejection film, not the Rayno S9 which I am interested in. One guy will reluctantly do the front with a ceramic film, but the cost is rather high ($850 not including the front glass roof). He said the tint actually made the heat worse! I am not sure if I believe him. There is another place in Brisbane (Solarstyle) that I will try calling tomorrow. I am wondering if anyone has tinted the glass roof, and in your opinion, how much difference that has made to the heat coming through the roof.
