CARPRO IronX Iron Remover: Stops Rust Spots and Pre-Mature Failure of the Clear Coat, Iron Contaminant Removal - 1 Liter with Sprayer (33.8oz)

Do you know if the car was parked in a parking garage that might have had some rust water dripping from the ceiling? I had it happen to my car and no amount of rubbing or polishing compound removed it. One day I tried using this iron remover which ‘magically’ turned the rust purple and it simply washed off. Good luck!
