Hi everybody. I created an account just to ask this question.
Basically I left my car at my parents for a couple of days. Their next-door neighbour decided to paint their house (external) and came around and offered to wrap up my car with a clear plastic drop sheet - the type you get from a hardware store when you want to protect surfaces from dropped paint when painting a house. The sheet was taped to the alloy wheels, not the body of the car.
I arrived a couple of days later and unwrapped the car and found that all my panels have areas of a dull grid-like pattern on them, especially over raised areas where the plastic drop sheet would be touching/rubbing the car the tightest...
I have attached several photos below. Note the dull and grid-like pattern. They are present on just about every panel....
I have tried just washing and also using a polishing compound - no change.
It's like something in the plastic has infused itself into the paint work.
A quick google has found only one similar report and the poster had no real resolution after polishing/cutting/waxing. His post is here:
https://meguiarsonline.com/forums/showt ... d-my-paint
His photos show the exact same dullness and grid-like pattern and it was also at the hands of a plastic sheet cover.
My parents don't speak English enough to discuss finer issues and exactly what was said between them and the neighbour's contractor is completely unknown and unknowable at this point.
Does anyone have any definitive explanations and solutions for this other than a full repray?
paint damage from clear plastic drop sheet?

i have seen this happen many times, BUT i can't tell you really what causes it. it will most likely need a repaint. i would find out who the contractor is AND if he is the one who covered the car he should have insurance to cover it. if the home owner covered the car then they should have home owners insurance that should cover it. good luck it could get messy. PLEASE LET US KNOW HOW IT PROGRESSES.

So was your paint job on the car fairly new or just factory paint?

Hi Darrel. The paintjob is neither factory nor new. I repainted the car 15 years ago from factory boring silver to ultra glitter metallic silver.

On the box or container of every corona treated plastic I've ever used is the warning "Do not use on wet car".
If the plastic was on there for a few days even overnight dew would be enough to cause that damage. No, I don't know why it does it,nor do I have a simple fix. I'm always careful to make sure the car is dry before masking up and remove as soon as possible. Chris

An educated guess is probably that you or experiencing migratory plasticizers coming over from the plastic sheeting. We do see this in lacquer furniture coatings here in the US. In homes house painters will cover older furniture (sometimes just 5 to 10 years old even) with this type of sheeting and get the same kind of patterning. No amount of cutting/buffing will usually fix it. We end up going back down to bare wood/metal for complete refinishing.

This is a Bad situation the contractor was trying to do the right thing. Proving all this in court is not gonna be an easy deal crying shame to the car owner. I have never seen or paid attention to any warnings on the Box I will have to look for it. On a side note I use a Lot of 3M Over spray Protective Sheeting I wonder if it has this warning? I only use it on Dry cars though too. I love this Plastic sheeting wrap works great! Dennis B.

Would the forum think that this damage is beyond a “paint correction” sanding and polishing the damage?

Yes, The Plastic gives off a Gas, that gas penetrated the Clear coat.

I've never been able to successfully do a cut and buff when this has happened either on cars or furniture surfaces.
