For what its worth, bought a new white Toyotoa Celica GT 5 spd convertible in "88, picked up on July 3rd for a 2 week vacation trip to Key West from Ohio. 2 weeks after I got home I noticed an "orange haze" on the hood, and took it back to the dealer. Talked to the dealership shop manager, they gave me a loaner GT and in a week mine was returned to me, looking good. A moth later the same "orange haze" showed up on the trunk lid, and I went back to the dealership, where I talked to the Asst. shop mgr, who related that this was rail dust caught between the paint and the clear coat, having not been cleaned property, and that it was oxydizing/rusting. He related that, as had been done with the hood, they would scuff the clear and repaint and re-clear the trunk lid. When I questioned why rust was left trapped between tow layers of paint, I was told it was "standard procedure".
I was a plain-clothes police sergeant, in slacks and a suit coat and a tie, with a small 45 in a shoulder holster under my left arm. As you can imagine, I found this revelation VERY interesting, and asked to see the general manager. After a 30 minute wait and repeated requests to see the general manager, and repeatedly told He was busy and would see mean in a minute, I became a bit perturbed. I took off my jacket and badge clipped to my belt, and with my 45 in plain view, announced in a loud voice that I was tired of waiting to see the "boss". Probably 20 customers in the showroom noticed and scurried out to the parking lot in less than 2 minutes. I was in the General manager's office in less less than a minute afterwards. He explained that what they were doing to remediate the "problem" was proper and I had no recourse but to accept it.
Long and short, after a year in negotiations and arbitrations, I received an award equal to my purchase price, the interest I had paid over the 18 months of the loan, and $1500 for travel expenses, attorney fees, and costs.
