Strange marks on Cayman GTS front trim

[PhantomPH]

Could anyone shed any light on this before I speak to my OPC after the bank holiday?

See the below images - I washed my car yesterday and noticed two 'rust' marks on the black trim on the lower grille openings on BOTH sides of the car. I've not noticed any clips there during other washes and this marks have only just shown up this week (I washed car last week and didn't see them then).

Any thoughts? Should there be clips there and I've just not noticed before? The rusty marks will not come off when cleaning.

Many thanks!

My trim is in great condition - all marks bar the brown ones are road grime and 'dirty rain' spots from the weather we got literally 15 minutes after I finished washing it!

Has something metallic rested on it and bled rust onto trim. Seems unlikely but can't imagine what else it could be.

[tracydeedance]

Could be fallout especially if near railways or factory's

[PhantomPH]

Nothing could have rested on it. Doesn't look like a place where clips would be, but another owner could correct me on that one.

The worst one looks like something has been clipped on there. Annoying that I cannot get rid of the marks.

[PhantomPH]

I think what has thrown me here, is that it's the same spot on both sides of the car.

Is there a screw holding in the indicator above which has rusted, with water dripping slowly off it in the rain onto the lower trim. Would explain same mark on both sides.

[PhantomPH]

Good thought! I will take a look.

ETA: Nothing that I can see or feel above the area.

Have you had it from new? Did the previous owner have the aftermarket grills fitted?

[PhantomPH]

No, it was part of someone's collection. Do you think there may have been clips there that I've not noticed before, but have come off this week?

The Zunsport grills are clipped in place, but I don't have them so how and what with I am not sure Somebody who has them I am sure will be along to comment.

I wondered Zunsport grilles but I'm not aware that anything in that area is metal. The Zunsport clips IIRC are good quality and not prone to rusting I'd have thought.

Pretty sure they're marks left after Zunsport grilles have been removed - the locations match where mine are. Very odd though as the bumper trim is plastic so the marks should come off if they're from rusty water.

The bumper inserts can be replaced but as you have the external GTS pack they're painted so it will be more expensive than usual.

I would put my money on Zunsport grill have been fitted at some point and you have just not noticed befor

[PhantomPH]

Thanks for the feedback gents - it does sound like that could have been the grilles. Wonder why he took them off before selling - perhaps needed the extra few quid from eBay to fund the brand new 911 he was trading it in for...ha ha.

It would be Zunsports. I can confirm that there aren't any clips there from the factory.

The grilles will probably have been removed by the OPC as they're not Porsche parts.

[PhantomPH]

Thanks guys. Will just do my best to clean up the marks. Annoying!

Or add them back on. I have already had a stuck rad fan from stones so fitted them
