Paint on door wearing or chipping away

Has anyone had the problem of paint suddenly just appearing worn on the front door trailing edges about knee height? When this happened after a trip to the dealer on the driver side I thought they did it. They agreed to have it touched up. Now a few days ago, after another dealer trip, I saw the begininnings of it again on the passenger door this time. Both times it seems to start out slow with just the appearance of white (primer) at first in maybe a 1/8" section along the door. This last time I've seen it enlarge very gradually over a few days to about 3/4" in length. There is an easily seen dot of white primer as well as a faint line along the door trailing edge that get more noticeable each day. It happened just like this the first time on the driver door too. There isn't anything I can see in my garage that could hit this and I never park next to anything that could do this. It's almost like the paint in this locatiion is very thin and being worn away when a person brushes it getting into the car. Anyone else notice anything like this? And the car is always covered during the day too. Any ideas out there. I'm stumped.

 

I thought at first that this was some sort of chemical attack like brake fluid. And the first time as the spot got bigger day after day I thought I was imagining it. I did not notice it until I washed the car many days later. This time I didn't notice it until a few days after the dealer worked on it. And it was very very small but grew larger within days. I touched it up this morning with the paint the painter mixed for me the first time. There just isn't anything in my garage or where I part it that could do this. And you have to open it into something to get at the edge to cause this sort of damage. I almost always drive alone but my wife has been with me a couple of times lately and I don't think she could have done this unless the slightest brush in this location would cause something like this. The paint must be very very thin. The sheet metal in this location is sort of thin too so it's probably difficult to get enough paint along this edge.

Klatu...yes I got mine at the end of Nov. too. Maybe it's related to some of the early cars?

 

Bob,

The funny thing is, this didn't start happening until I had my car for about 4000 miles. Then after one trip to the dealer I noticed it beginning about a week later. I suspected brake fluid on someone's knee and it's just at that height. This second time the usual alignment mechanic was the passenger and the Toyota rep was driving the car I think. Now it's the passenger door. I gave up today and cleaned the spot and touched it up with the paint the painter mixed speciall for me. So we'll see how that holds up for now. But I swear once the white spot appeared it grew in size during the day without anyone touching it. The photo of the 1st door even looks like some sort of chemical attack. Needless to say, I'm through with this dealership. They've given me more than one reason to take my business elsewhere.
