Ok... so after washing my REX... seems like the back bumper, by the exhaust turns black from exhaust soot in just a few days.... I hate the way it looks ! And frequently washing the car or letting it go for while doesn't seem to make a difference. Regardless, the soot is tough to remore. Plus it gets into every nook and cranny. My car is RED so the soot really shows... and makes the cars rear look ghetto.

I heard about some stuff that's supposed to be really good at removing ehaust soot but can't rememeber its' name or a purchase source...

Any help would be appreciated ..... either PM me (AOL IM is "karken29" YAHOO IM is "karken_07960"), post this thread or PM me ....

Thanks,
Rich

BTW... At WOT (Wide Open Throttle) my Air/Fuel Ratio is 10.2 : 1 .... otherwise... I'm at like 13.8 and up...
