"Probably" does not work here, if yer near any senior guy on this thread, pop over an show yer car to them an get an idea of what the marks are. Remove tar with clay only if you know what yer doin! Clay kits start around 2.5k onwards, an plenty of shops stock them in Lahore. Tons of people here who can do it, or your most welcome to pop over to me an I`ll teach it to you.
