Glastonbury Fallout

So asked to look at the car belonging to one of the first responders at Glastonbury.
Someone had sprayed Coke (full fat) over his car.
Of course after 4 days it was baked on.
Knows it was Coke as they left the can on the roof.
Had a quick wash, clay, IPA, decon and then a light cut. Epic fail.
Only just about got it off the windscreen.
Looks like the same damage as sun cured bird strike once you cut through the sugar.
Even etched the plastics....and we let our kids drink this s**t.

So going abrasive clay, wet sand and rotary.
Thoughts?

As Cola is strong in phosphoric acid, there is a chance it has been eaten into the paint.
However it's also extreme high in sugar, so it could have been "caramelised " onto the paint.
My first try would be wet cloth (warm, hotisch) and leave them to soak for a while on the spots, see if they get sticky again.
Try if there is any sugar remains first to dissolve them.

If it's acid damage, it depends how deep it's gone, if there is any remedial action that corrects that.

From Wikipedia:

Quote:
Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution is acidic enough to be corrosive.
What will have happened is that the water will have evaporated in the sun, but the sugar in the Coke will have acted as a humectant and kept a certain amount of water present. This will have ended up as a sticky concentrated phosphoric acid solution that will almost certainly have etched the clearcoat, if you can see marks then I'm pretty sure that's what it will be, since the syrup will have washed off very readily.

Sounds pretty bad @typhoon - I remember a friend getting his car 'done' with shaving foam after his wedding and it ruined the clear.

Good luck, can't wait to see the pics.

Green star all over followed by careful use of a steam cleaner, I would not set the heat to more than 60 degrees... Be careful.

Just give him it back and be honest and say you don't really know how to get it off without knowing how far it's etched into the clear, better be safe than sorry.

Had the worst with baked on bird strike left all summer, ate through plastics and paint and did a reasonably good (customer opinon) correction including some clearcote breakthrough rework. We will see how we get on.
