    Hi all!

    Here's an Audi A3 that I did over the holidays, but I'm just getting round to posting it. The manager of an apartment building called me up and I really didn't understand what he was trying to tell me about the damage on this car so I told him I would come and look at it. He said it had some "stuff" on the hood and windscreen that didn't want to come off. Hmm, when I translated "stuff" into "customer" language I knew I was in for a treat... When I arrived I was introduced to the owner who happened to be a really hot French bird... single too... :wall: (I'm married :)). Anyway, enough about the sexy French bird with an unbelievable body and big, brown, pouty eyes and... sorry.

    Like I said, I knew I was in for a treat, but I wasn't expecting this >>

    I was thinking "Sweet jeebus, what the hell is that???"

    It was obviously some sort of salt and something else compound because it had dripped on her car from the ceiling in the garage. Whatever it was, it burned the paint and not a single chemical I had would even put a dent in it. I even used Super APC undiluted and still nothing. By the time I arrived this stuff had already set like cement. So the only choice I had was to wet sand it off. I wanted to take off as little paint as possible so I used 1500 grit to sand it off. Using 1500 sure took a lot longer, but I could monitor exactly when I was through the mystery mix and on the paint. After polishing I took paint readings again and on average only took off about 3-5 microns. Here's some during shots >>

    After being compounded with a wool pad and Insta Cut #2. Normally I would have used a lighter polish but Audo/VW have THE hardest paints in the world... well at least here in Europe anyway.

    The car got an ONR bath afterwards and was waxed with Insta Finish Premium Wax.

    You can see here in the reflection where the paint is a bit wavy... this was the "burn" damage I was referring to. It burned little "valleys" into the paint!

    And NO, I didn't dress the arches :). Waste of product if you ask me.

    Wow, that is some great work getting it back to that condition. Looks like something leaking in the parking deck. Have read other people have same issues and it being a PITA to remove.

    But umm....where is the pics of the girl? :) haha

    Thanks guys! Yeah I wanted to snap some pictures of the girl, but... :) There was actually another guy that came to me while I was doing this car and his car had the same damage. Unfortunately some jackass tried to polish it out and burned through the clear in several spots so he needs a repaint...

    Jeez, I have got drops like that on my car before from car parks but fortunately they have come off without much trouble. That stuff etched like crazy though! I was amazed at the "waves" in the paint that you captured.

    some SOB actually poured acid on a car? If I'd catch that in the act, I'd make SOB drink that acid, and slash some in his eyes...how do you like that? I'm still pissed off, because somebody keyed my daily driver, as well as covered it in with dirt, while it was parked on my driveway...and now I have video survillance cameras...
    Nice save on this one, by the way...

    That is the lime from the concrete that the water pulls out of it when in goes between the slabs in a parking lot. It drips down on the vehicle and the lime stains the paint. This is pretty common in parking lots. I had to remove the same thing from a Bentley once.

    To the op, great job, I know how much time you put into removing the stains.

    Damn that sucks! Well I'm pretty sure it wasn't acid now, but it did etch its way into the paint so it must have been pretty high on the pH scale.

    Thanks buddy! I put about 2 days into it... What did you remove yours with?
