just bought my Land Rover a few weeks ago and love it, she is white in color, she had some rust stains hear and there, so I whiped it down with CLR in a spot that didnt show just to make sure it didnt effect the paint, and it didnt. It worked very well, dont expect to get ride of bad rust.If you catcth a stone chip that just started to rust, or where your door hinges rusted and you have a stain running down, it will work.Just keep some clean soapy water and wash off once you cleared the stain away, and apply wax.
