So, my wife's Mercedes had a rock chip. I put touch up in it, and allowed it to dry. It was there for more than a couple of weeks, but shortly after, I noticed the spot/chip was back, and below it... the paint has run down! Is this normal?? Wow.
It was Mercedes OEM touch up that I bought from the dealer.

I'm assuming a clay will remove this like it would over spray ? (I'm not an expert by any means, so I'm not even sure that's right)

Anyone seen this before or have any advice?

Look under the two black chips. It's subtle, but it's there.



 
Has anyone had this issue? Touch up paint running down the panel more than a week later...

My wife has a Mercedes (2018 model). On the front bumper, she got a large rock chip that I filled in with Mercedes touch up paint from the dealer.
I let it dry and it seemed to be fine, but more than 2 weeks later, I noticed the chip was showing again, and the paint has run down onto the original factory paint.

Has anyone seen this before? I’m hoping it will come off with a clay bar. (Since clay was originally made for overspray)

Before I attack it, I thought I’d ask here if anyone has any tips or advice.

I’ll post a pic below.

Did you clean the area good with a solvent before painting? Mineral spirits or something similar. Rubbing alcohol and water mixture at the very least. I assume the paint ran down very shortly after you did the work. Once pain sets up it won’t run? You did shake the paint goo$ before painting?

No solvent but I did alcohol. I did shake plenty.
It didn’t run until more than a week later.

If it was a week later there is something wrong with the paint. Once the solvents in the paint completely evaporate it shouldn’t move. Enough solvents have evaporated from touch up paint for it to remain completely stationary after about 10 minutes. Take a little of the paint and put it on something else and see if it sets up completely.

Good idea in testing it. I will do that before using it again.
In the mean time, any idea on how to remove it from my original paint? When the weather is right, I'm going to fully wash, clay, and polish. I'm hoping the clay will work, but not sure if it's the right thing to try first.

If clay doesn’t work you may need a solvent to remove the dried on paint. Try Dr Colorchip next time. I’ve used it on 4 different cars and have been very happy with the results each time. There are plenty of how-to articles here on AG about Dr Colorchip to review before applying.

Its not the prep work. Its the actual paint being sold by the dealership. The touch up paint from tesla is really runny and doesn't hold as well as honda or Toyota touch up paint. Theres nothing you can do except source the paint from somewhere else. If you have a connection to a body shop they can make some paint for you.

Thanks. I did a full detail on the car for the first time. I'm going to post another thread about it, but clay basically took it off.
I'm going to try Dr. Color Chip next.
 
Hey Scott,

I noticed you have 2 threads for the same topic?

I merged them together. Not sure why...

Hmm. Not sure why. One thread was regarding my overall first time to full detail with my DA on this car. I mentioned the paint in there, but it wasn't a focus? Maybe that's the confusion.

Sorry.

Yeah I'm not sure? I was reading through Detailing 101 and came across two threads about panit chip repair paint on a Mercedes?

Here's first thread

These two posts were in the second thread - look like same kind of thing except the picture is smaller/attached?
