i posted this under "washing by hand" and only received one reply. although helpful, i thought i'd seek additional opinions. so here is the same post. oh and if double posting is against forum rules or anything like then feel free to remove this thread.
so i had parked under a pecan tree and noticed a few brown stains on my bumper and hood from pecans falling onto the car (damn squirrels). the stains have faded a lot on the hood. however, the bumper seems to hold on to the stains a lot better and haven't changed in appearance since getting them about 2-3 weeks ago. i'm guessing it has something to do with it being plastic vs metal. anyways, i consulted the dealership about the stains, but they informed me that the stains have settled under the clear coat. is there anything i can do about this? or am i just SOL? would i be able to approach this with rubbing compound or something?
