Well it was a sunny and warm day here so I decided to wash my car and procrastinate from finals :P I'm at school so I park ouside, half the time under a roof and the other not. I've been busy lately so today was the first time I washed my car in 6 weeks. So i went to a local self-wash place and washed my car with my own wash (meguiar's nxt generation car wash) and microfiber towel... i started off with my trunklid and this was the first thing i noticed after getting the dust and dirt off...




... and i'm like



I scrubbed really hard, but it was apparently futile. those pictures are after i washed and dried my car :/

when i run my fingers over these brown spots, i don't feel anything :/

i always wax my car after i wash it, but i didnt wax it this time cuz im waiting to get this crap off

do you guys know what it is? could it be tree sap? i always avoid parking under or near trees.

 

/i have a mysterious orangy bronze residue on mine too. i have no idea where it came from. it looks like rust but its on plastic so i dont know what the hell it is. im getting it painted this winter and hope to never see that shit again

 

theres a thread about it, but forgot what its titled...id say its paint failure under the clear...oxidization?

 

yeah im hoping it's not this :/

u try clay bar?

 

use clay bar, that shit comes off, its from the rotors i believe,

 

Your car has melanoma.

 

+1 for the clay bar... might as well give it a shot

 

to the OP.. looks like tar or tar residue from the road, try some goo gone or a tar remover light on a microfiber

 

Looks like what is commonly knows as rail dust. Use clay bar or 3M Scratch-x. It will come off.

 

^ What he said. Also pick up some bug and tar remover. I use this stuff...

 

I have the same stuff i thought it was coffee stains
