I just purchased a 1989 Volvo 240DL wagon. It's in exceptional shape, except that the clear coat has bubbled on a small section of the hood. There are probably four 1" long and 1/4" wide bubbles, and you can see the moisture collected underneath them. Since these cars have such a reputation for rust, and this one's perfect other than that, I want to take care of this. I need this car to last 10 years. Do I need to see a professional--can he patch it or would I need to get the whole hood done? Should I pop the bubbles to release the moisture and nip the problem in the bud? Is there a kit or home remedy I can try first? Thanks, guys.
