    Covered car with plastic sheet --> stained my paint

    Hey fellas, someone posted about Meguiar's products on 6mt.net so now im here after some online research for my big big problem:

    I covered my car with a plastic cover (regular plastic sheathing) since I did not have a car cover the day after: 1/ My car was Egged (yes I washed that off) and 2/ there was Hail falling randomly the day after that. I left it for a few hours during the cold day and later that nite for almost the entire night
    Now I am left with this:



    after waxing (yes Meguiars), still visible:



    the new wax shine makes it harder 2 see but only at some angles and the worst is on the side:



    There is also a purple-ish mark that must have come from the small lettering on the plastic. Im assuming the vapor/moisture trapped in the gaps somehow marked up my paint... And yeah I had no clue plastic sheathing would do this, i know its my stupidity and I should have known.. any help/advice would be awesome, thanks_

    You say you washed and waxed?

    Did you do any other steps, like paint cleaner, etc?

    It looks like moisture is stuck in the paint film. Try spraying a 50/50 mix of water/isopropyl alcohol, let it dwell for 30 seconds, and wipe off. If it is moisture, the alcohol will act as a drying agent and pull the moisture out. If it's not moisture, the alcohol won't hurt the paint, and at least you'll know that the paint needs to be buffed.
    I want 4" Softbuff pads!

    Sounds good, thanks, i also heard of using vinegar on another site i cannot link at the moment, as far as buffing, it should work but even if its IN the clearcoat? When i run my fingers over any of the surface its all smooth.. LAst thing i wanna do is have to sand this down (bodyshop) n have new black paint not matching the older black paint (10 months old) not to mention cost

    Oh boy..... I would try the alcohol like gbackus suggested, but other than that, I am at a loss. Perhaps give ScratchX a try and really work it into a few of the worse spots to see how the paint reacts???

    mannnnnn if you, the moderator are at a loss, it saddens me..! but yeah, ill try the alcohol, even vinegar, polish, different compounds, and buffing from a shop to see what might work. If i end up wit dull paint, ill have to repaint it anyway.....

    I had to do a double take at first, I couldnt figure out what was wrong, but wow. I dont think I've ever seen this...

    I'd start by stripping all the wax off with a body solvent and then work your way up from 80, to 83, 84 w/ rotary, 85, and if need by try the other Meg's Cleaners, Fine, Medium and Heavy cut, but all and all, I am at a complete loss.

    My dad suggested this, were both still confused...

    Perhaps there was some substance or film on the plastic that was triggered by moisture.

    Or did the sun come out after it rained and the light amplified by the residual rain drops refracted though the plastic and yellowed your paint? I'm utterly lost.

    yeahhh

    Yeah i was very truly perplexed and i knew others would be.. since I cannot feel anything on the paint, i did at first but prollie jus dust build up, I am at a loss as well.. Im beginning to agree that the paint might have faded but there was very LITTLE sun out, it was Cold. either moisture is trapped in the clear coat or its fade.. I think its both moisture and plastic material in the clear coat... well THANKS man ill try some of those things_

    Hey,

    I would still try the alcohol and then ScratchX over a section. I have heard of plastic causing trouble when there was high heat, which caused condensation under the plastic. But I have not seen staining quite like that. I will see what else I can find out.
