I have a 2006 Honda Civic, and the paint on the roof is beginning to deteriorate.
It looks as though maybe the top coat is discoloring and coming off, revealing the coat underneath, which seems to be intact. The affected area is currently about 7" x 2" (20cm x 5 cm) and seems to be slowly growing over time.
Honda seems to be aware of this problem and released a technical bulletin a couple of years ago, extending the paint warranty. Unfortunately this expired before I started to notice a problem on my vehicle. So if I am to fix this, it will be at my own expense.
So I am trying to determine:
Is this only a cosmetic problem, or is it more serious? (For instance, is it likely to lead to rusting of the sheet metal, or any structural problem?)
Is there any way to fix it short of repainting the entire roof? (I would probably have that done professionally.)
Assuming that, in the short term, I don't really care how the car looks, is there any advantage to fixing this in a timely manner? Might it be cheaper to fix it now than later? Or could I put it off indefinitely, until I want to sell the car, or until it looks so bad that I am embarrassed to be seen driving it?
(I read Roof paint peeling badly, with rust -- what to do? but their problem is a lot worse than mine.)
