Those "bubbles" are not bubbles at all! Gentlemen, that is RUST that has formed below the surface of the paint. While it can be fixed as I just did mine (I repainted the sunroof and took it down to bare metal with oxide primer) it WILL eventually return, as the sunroof is not made from the same grade of metal as the rest of the car. Any rust which forms will in time return, as will all cars rust given enough years! <P>Yes, given enough years, all our Reattas will rust somewhere, as even the factory couldn't and surely DIDN'T prime them that well! Moisture does and will get under the paint in time, and while it can always be fixed, it does come back given time. One can only hope to match the paint and retard the formation of rust, but rest assurred....nature and the elements WANT OUR CARS BACK! Just see how long we can keem 'em! It's a losing and constant battle, but I plan to win for a while! Get it done now or later may be much more work than you bargained for!
