I haven't detailed the car in atleast a year, like I'm talking atleast a year since its been clayed or polished.. it sees wax every now and again, just haven't had the time to do the proper job. I have some spare time and I'd like to wetsand it. Best grits to use? I have all the detailing products and machines I need. All of the paint is original minus the hood, front bumper, fenders. The paint looks rough. Not gonna lie I've neglected it.
