i recently went for my in camp training and parked at the camp in tuas for one week. didnt move the car at all for the whole week..the weather was very hot throughout except for some rain in the middle of the week. as expected, by the time i out-pro my car was very dirty so i immediately brought it home and washed it. however, after washing it twice, the paint is very rough and dry now. what should i do? any advice is much appreciated..btw my car is a black e36 316i...thanks!
