3M PRESTIGE SOLAR FILM has no metallic properties, so it won’t corrode.
If you don’t like conventional window films because they change the appearance of your windows or reduce visible light transmittance, here is the window film for you. 3M PRESTIGE window film is optically clear but stops more than 95% of infra red heat. That’s a 50% cut in the total solar heat passing through the glass – and because it doesn’t corrode you get a 15 year manufacturer backed warranty. Also, the absence of metal guarantees freedom from interference with mobile phone signals, which can sometimes occur with metallic window film.
