you have almost certainly rust through the corner of the door. every pinprick of rust needs to be removed, and then the structural needs of the door as well as the cosmetic ones need to be addressed. pay special attention to the fact that rain water is supposed to enter the door, and is supposed to exit by drain holes in the bottom and often right near the back corner. because that complicates things greatly. now, is it possible to fix the door? maybe. once the trim panel is removed, and possibly electrical stuff removed from teh door if any goes down there, it might be clean enough to permit grinding out all the rust, and welding in clean metal. you may need to cold-galvanize the area as well. then the inside and outside need to be de-painted, solid primer like acid bonding stuff applied, then paint primer if needed for that chemistry of paint, and final paint. it's a lot of work. much better to always touch up dings when they happen, even if you end up with a pimply appearance on the car. if it ever gets ugly enough, you can pay somebody to sand out the imperfections and topcoat it with new paint and clearcoat. -0- a lot of folks will buy a salvage door and install it instead if the appearance of an 11-year old car is that important. |

| I'm looking at a used GTS and surprised to see rust on it. Would that indicate it has rust underneath? The brakes look exposed. Is that normal? | |

You mean rust on the brake rotors? That's no big deal. Means the car has been sitting around, that's all. If you mean body rust that flakes off with your fingernail, that's a big problem. |

unlike drum brakes, the calipers on disk brakes sit on either side of the drive shaft's brake target, called a rotor. they squeeze in from both sides. for cooling purposes, you don't put shields over this stuff. and if you have pretty wheels with cutouts or spokes, you will see a (generally somewhat) rusty caliper with these THINGS overhead and to the side. it's a feature, not a bug. they work great. rejoice in seeing them. |

Here is a pic of the crap body repair that was done on my Altima, less than a year ago. The paint cracked in this area and I'm now seeing some rust staining around it. It will be re-repaired at another shop. I assume it is only superficial at this point. Should I plan on keeping it after it's fixed, or will it come back no matter what?  Yes, that's overspray and sanding dust on the rubber boot going into the door. Don't get me started! |

Replying to: Mr_Shiftright (May 27, 2005 3:25 pm) You think it would be worth a shot? The metal already seems thin by the rust spot. When I tap on it with my finger it sounds more tinny there. What do you think?

That might last a year or two. I'm just worried that if you pop the windshield and the frame is weak with rust that you might not get it back in again very easily. I'd kind of have to see it, how bad it is first. |
