Hi Guys/Gals Great forum you have here, I have been lurking for quite some time gathering tips! I have a question maybe some of the gurus can answer. I have a 2008 Shelby GT500 that the previous owner used as a show piece for his business Krown Rust Control, This mess is everywhere on the undercarriage... Now that the car is being driven and enjoyed it's turned a black filthy oily dust collector mess... What product can I use to remove this Yuck? Is there anything I can use to cut all of this crap off?? Cheers!
