here on pakwaheels, i have seen complete rust buckets being converted into lovely sillky flawless mirror finish, far far better than the original paint from factory..
many were done in karachi, offcourse it took time, effort, patience and money to get the desired result, just need to find the correct person to get the job done...
i have restored a car in lahore 15 yrs back from a normal workshop, nothing fancy, the parts sprayed in my presence were way better than those done without me...and yes it had that lovely finish and lasted very long
