I know I am really pushing the limits because I took this thread into a different topic but I just have to show what Moniz is talking about
You see all those red spots, those were once rust spots that are on every car but especially visible on white cars. When Iron containments attach them selves to your car, they will rust on your paint degrading their level. A thorough decontamination will remove that. I can do this service for you or I can explain how you can do it your self but not in this thread, PM me or request me to make a thread.
Let's get back on topic people
Edit: This customer's car is a mere 2 months old at the time of the detail.
