I had mine done by Justin Castillo in Salt Lake. Fully wrapped like @floormat and have held up for a year. Yeah we don't have the scorcher heat that Scottsdale has, but I think in Los Angeles you'll be fine if you get an experienced installer. Justin has ten years. It gets pretty hot in Salt Lake City in the summer but I don't leave my car in the sun all day. No issues with Salt.I'm curious how the chrome delete on your side mirrors is holding up? Any rips or gashes in the wrap? Any issues with the mirror folding?
