Magnet faded the paint?

[ProntoPrinter]

Anyone ever see a magnet do this to paint? I’ve seen it work in the opposite where the paint around the magnet faded leaving darker paint underneath or the paint getting scratched from dust underneath. I’ve never seen the paint fade though…

It is recommended to remove the magnetic prints at least a couple of times a week otherwise they can cause problems. How long were they mounted on the vehicle? and how long were they not removed?

That looks like moisture penetration into the finish/protectant. It most likely will gradually fade away with exposure to the air.

This is why I hate doing magnetic signage. People slap them on their vehicles, never move or remove them (regardless of you repeating over and over that they need to), and this is what you get Then they usually blame the company that sold it to them. That might buff out if you're lucky, depending on how deep into the finish it is.

I wont do magnets for vehicles anymore, they usually fall off or mess up the paint and always look tacky.
I would do an interior "baby on board" style suction cup sign on the window or just print them a couple copies on something easily removable like 3M 40C vinyl before I use magnets.

That isn't fading, it is moisture that was trapped behind the magnet because they don't remove the signs on a regular basis.

I always try to steer clients away from magnets. If they insist, I tell them that they need to remove and clean them and the surface weekly and when I give them over, I put detail wax on the back of the magnet and the vehicle and tell them that they should detail wax the magnet and vehicle before reapplying to the clean surface. Not that detail wax will do much, but it will assure that there is no micro sand or debris that will scratch the clear coat. Just remember that magnet is a clay product, which is essentially dirt.
