Hello folks,
I am new to (super basic) detailing. I am prepping my 5 year old Forester to detail for the first time. I have been checking the vehicle's paint by each square foot and noticing loads of issues.
On the back I see a lot of rust spots, looks like a super small dust particle (pollen size) but if I spray Iron X, the point turns purple. I suppose, that means the salt has eaten through the clear coat and paint exposing the metal underneath. This is the car that was ceramic coated when new. Afterwards, I have been regularly washing the car at a local car wash place as I am an apartment dweller and we are not allowed to wash the cars in the premises (plus no running water or electricity in the parking lot).
Here is the picture. You may have download the picture and zoom it in to be able to see better. The rust size is so small that it is difficult to get a clear picture using a phone. Hope this at least gives you folks some idea of what I am talking about. I have made red circles at the spots.

Any input in fixing this or strategy to prevent this getting bigger is appreciated.
Thanks a lot in advance.
