one of my friends has a silver hyundai, and he bought a bra for it a few months back. whenever he washed it, he would leave the bra on...probably taking it off every month and a half or so. well when we went to go wash our cars today, he took the bra off, and there is an ugly yellowish discoloration on his hood. not the whole area the bra covered it, but near the front...a few blots of it. i had some meguiars paint cleaner (step 1 in the deep crystal system), and we rubbed the hell out of the surface with it. didn't do anything at all...made the surface squeaky clean, but the yellow tint was still there.

he's desperate to get it out. it might be a hyundai, but my boy takes care of it like it's a stook

if anyone could help us....please let us know...thanx

 

That's a big 'no-no' in car care.....leaving the car bra on for a lengthy amount of time that is. Always remove the bra prior to washing.

He might try a clay bar. They take off surface contaminants, dirt, etc and is safe as long as you do it right(use plenty of lubricant and knead the clay often to use the clean sides). My .02cents...
