Need some help-removing foreign substance on hood

I'm currently doing a black Infiniti G35 coupe (think it's an '05ish model year) for a referral client, and he bought it off ebay freshly detailed...yeah, uh-huh, freshly detailed. Anyway, I had a chance to look at it a couple of days ago in full sun and it's pretty screwed up. There are swirl marks all over the place, buffer trails all over, and this:



It came up from TX on a car hauler and he said it definitely wasn't there when he saw the pics on ebay. He contaced the seller and they offered to reimburse him for any costs associated with detailing the car or getting it re-painted. I have a sneaky suspicion that it might be motor oil. I think it was sitting underneath another car on a hauler and the car above leaked on it. I had to ONR wash it due to cold weather in STL, then clayed the hell out of it with Adam's grey clay. Then tried some spot polishing on hood to try a few things. Here are results of Flex 3401, white 5" LC pad, and Menz 203:





I was pretty surprised by how well 203 cleaned up the swirls and oxidation and lighter scratches. The above shot is after a Menz Top Inspection wipedown as well, so no filling.

The polishing helped remove some of the substance, but not all obviously. Was going to give it some PowerGloss action tomorrow morning with either the 3401 or 3403 rotary. Wanted to see if anyone has suggestions for getting this type of crap off? I'm afraid it may have gotten into the CC too much already. Any suggestions? Thanks.

Oh, and for grins here's a clay shot:

 

I would compound it i think it will be only way to get it out.but hard to say cause i not there to see it in person an i'm sure after all you did will need a compound.

 

Is it on the paint or IN the paint. Smooth surface or sticky?

 

In a perfect world you would do a decontamination wash to see exactly what you are working with but with STL weather that is not much of an option... I would start by wiping it down with prepsol, then clay, and then use a "paintwork cleanser" (something such as FP or #80) and keep on working it until you have the contamination clean enough that you can determine your course of action.

It is a terrible feeling when you can see the defect, can not feel it, and can not measure any damage with a PTG. I have seen a couple of cars recently come off of transport trucks with etchings that have changed the "shade" of the paint on the area contaminated.

 

Thanks for the feedback. I'm heading our right now to try a few things including compounding. Keep you posted.

 

If you have a look to the right of the biggest chunk of stuff you will see a crescent shaped mark. Typically this is associated with an egg being thrown. Run your fingernail over the area, there is a good chance that the paint is is all chipped up here. Have a really good look and let me know.

 

911 - yes, that caught my eye there. That little section actually has chipped paint, like something metal fell on it and scratched it to the primer. That's why I'm thinking it might be oil. Maybe a lugnut fell from the car above and then leaked on it, but I would think there would've been a lot more oil spilled on it. I ran my finger and fingernail over it and the area is smooth where the stain is (not the chipped area), so I'm fairly certain that whatever it is is down IN the paint.

I took my rotary, orange pad, and some SIP to it and before that tried some PowerGloss, orange 5" pad and Flex 3401 to it. It cleaned it up a little, but it is still very noticeable. I'm starting to think he's going to have to have it re-sprayed. The seller offered to pay for it. I think I'm going to move on doing the rest of the car with SIP, orange, on rotary, followed by Menz 203, white pad on the 3401 for cleanup.

 

Id just get it repainted if he already offered to pay for it.

 

Yeah, those stains are ground in pretty good. Everything else is cleaning up well though. Here's a couple 50/50s on the hood:





And here's the hood after SIP, orange pad, Flex 3403 spread at 1100 rpm and bumped up to 1500, then back down to 1100, followed by 203, white pad, Flex 3401, speed 5-6:



Might be a smudge or two on there as I wiped it again after taking this pic. Merry Xmas everyone!!!

 

Nice correction work. That hood looks awesome. If that crescent shaped bit is chipped, the damage is from an egg. Yolk and egg whites that have a chance to sit on paint can be catastrophic. Funny thing, tossed eggs always leave a crescent shaped mark like that. The chipped paint is from the eggshell - very hard and sharp. Its going to need a respray.

 

Ken, you took the words right out of my mouth after looking at that picture. Eggs are one of the worst things you can get on your paint.

 

eggs or slices of balony

 

Hey, 911 and Asphalt Rocket, thanks for the confirmation on this. I spoke with the owner this evening and told him that he probably wants to start going down this path with the seller on ebay. Told him to make sure he has the original auction listing with all the pics and stuff. We agreed that I should polish out the rest of the car and then take the hood up separately.

Anyway, the hood gave me a chance to do some further work with my rotary. I've been using it on my car here and there, but it was nice to put it to work on some bad swirls/scratches. I think me and the rotary are going to get along just fine.

 

Do I want to know how you know about the baloney?

 

I really don't eat eggs anyway but know I'm going to add Baloney to the list...I would like to know the answer too...:shrug:
