What could this be on my paint?

[DonMTV]

Hey Everyone,
Last week I posted about starting to polish my 2003 Mustang Cobra http://www.autogeekonline.net/forum/auto-detailing-101/28829-i-am-goofball-started-polishing-didn-t-check-weather.html It had rained several times over the weekend.

Today was my day off and it was clear and sunny out. I decided to wash my car and see if I could continue my polishing. I saw something weird on the wing of the Cobra and thought it was just residue from the weekend rains.

I sprayed the car down and it was still on the car. I then sprayed P21S TAW over the entire car and used a microfiber mit to wash it off. I rinsed the car, and then foamed it with my foam cannon and pressure washer. I followed that up with a two bucket wash. This is what I was left with on the wing after using an Ultimate Guzzler to dry off the wing and trunk.

I thought it was residual oil from the Menzerna 85rd, but I actually had used IPA to wipe down prior to the rains arrival last Thursday. If it was oil, the TAW should have taken care of that. I rubbed a finger across it, and it felt smooth.

Next up was using a clay bar to see if it would remove it. No change. I broke out my Flex and used a Tangerine pad and Power Finish. Again, no change. Alright, I need to big guns. I tried Cyan, and Powergloss. Didn't even touch it.

Ok, what to do, what to do. I got my Porter Cable 7424 and Meguiar's 3" backing plate, and then used the 3000 grit Unigrit Finishing pad. I got my bottle of water and lightly sprayed the wing. Gave the pad a spritz, and started damp sanding. I did two passes, and wiped off the slurry. It really didn't help. I was at a loss, so I figured I should try the 1000 grit. This seemed to work, but didn't get it all. I was running out of daylight. I took out the sanding marks with SIP and Power Finish. The marks towards the front of the wing were not completely taken care of.

I will post pics tomorrow.

I really have no idea what this could be. I polished both the trunk and wing last week, and there were no marks on the trunk. Only the wing had these weird marks. Plus, when I ran a finger over it the paint was smooth.

Did you put any protection after polishing? That looks like some severe water spotting.

[DonMTV]

No protection. I didn't have a chance to finish up before the rain started. I had to work all weekend. It rained a couple of times since last Thursday too.

I would have guessed that it was severe water spotting too, but the trunk didn't have any spots at all. Usually claying would do something if they were actually water spots and that did nothing.

Is that a factory wing or has it been replaced at some point? That reminds me of clear on an antique coffee table after setting a hot cup of coffee on it. I wonder if that thing has been re cleared with a different type of clear?

[DonMTV]

Factory wing, no repaint. Your analogy is right on. I remember my Mom using mayo and cigarette ashes to take rings out on side tables. I could be wrong about the mayo, but there was some old wives tale cure for those water rings.

I will take pics tomorrow with my results of doing the polish, then damp sanding, and then polishing. As I said I didn't get it all off, but it is an improvement.

Looks like severe water spotting to me also but after the steps you took to try and correct it to no avail,could be a form of clear coat failure?:dunno:

Just for kicks, have you tried wiping it down with diluted vinegar and distilled water?

[DonMTV]

The hazing/spotting was apparent this weekend after the initial polishing last Thursday. It was completely revealed to me when I washed the car yesterday. That is what my photos are showing.

I attempted the claying, polishing, and then damp sanding. I polished out the sanding marks. This process removed most of the haze/spotting. I will be taking pictures in a little bit, and I will update this thread with what the wing looks like now.

I didn't try the vinegar and water as the clay didn't even make a slight dent in the haze/spotting.

The vinegar trick is for "Mineral Deposits on the surface", not staining that has penetrated into the paint.

Are you seeing pigmented color come off the wing when you buff on it?

It's not very common for staining like this to happen to clear coats...


I actually have a paragraph on this topic in an article, not how I mention i

Tracers Tracers - RIDS - Pigtails - Cobweb Swirls - Rotary Buffer Swirls - Holograms - Water Spots - Bird Drooping Etchings - Micro-Marring (http://www.autogeekonline.net/forum/hot-topics-frequently-asked-questions/22234-tracers-rids-pigtails-cobweb-swirls-rotary-buffer-swirls-holograms-water-spots-bird-droping-etchings-micro-marring.html)





Type III Water Spots
Type III Water Spots are spots that look faded or dull and are found primarily found on single stage paints after a water source lands on and then pools on the paint and is usually left to dwell on the surface for some measure of time before it evaporates or is wiped-off the surface.




It's mostly a problem with single stage paints since they are more likely to allow liquids to penetrated into themselves...

Components are often manufactured and painted outside the assembly line, that is things like wings are farmed out to other companies or divisions and then assembled onto the car at some point during it's trip down the assembly line.

That's why the color a component like a wing can match the car but actually be a different paint system and this is why you can see issues between the two different paint systems.

Mike,
The slurry didn't have any color, and the pads I used didn't have any color from the paint. As you can see I have a couple of spots to clean up. I will probably hand damp sand these areas and then polish.

I am still not sure what this could have been.
