guys, I am in the middle of a very serious situation. I had completely restored the exterior of my mehran 1996. it was a genuine painted car which was had rusted roofs and joints. I got it restored, spent a good 46k. got the car back on 26th july I.e. last week. after yesterday's heavy rainfall, I had noticed minor rusting on the roof again. day before yesterday I.e. friday, I had my car with the top cover at my office. heavy rainfall started at the evening, I took off the top cover and parked the car at the basement. upon leaving the office I had encountered heavy rainfall. by the grace of Allah I had safely reached home but the rain still continued. so I parked my car and covered it with the top cover. I had difficulty in putting on the top cover since it was wet. yesterday when I removed the top cover, I saw goosebumps on the pillars of the car and shading/discolouration on the entire car especially the roof.
please help on this
