I was taking off the pinstripes and the remaining glue on my car when I noticed my paint which is white had turned grayish in a spot (under the right side view mirror where the door panel ends). I have the same mark on the lid that covers the gas cap but that was there when I bought the car. Could it be that my paint was weak and it took off the finish? I used a bug and tar remover that was safe for the paint according to the bottle. The rest of my car is fine; im just wondering what I should do about it? I tried some compound but it didn’t work. Im not a big sticker kind of guy but should I put one over it to cover it if it cant be fixed?
