Welcome to genvibe and unfortunately, welcome to the world of poor quality paint and/or application methods thanks to Toyota/NUMMI. Unfortunately, there isn't much that can be done. Bugs will eat into this paint with ease, and you'll also notice plenty of chipping. I still have a big gash in the paint on my front bumper from where a bug struck the surface during the summer of 2003, it's quite ridiculous really.There are plenty of threads about the issue, this being one of the biggest, which is a poll.
http://forums.genvibe.com/zerothread?id ... ortunately, this is a part of Vibe ownership, sad as it is. If you have a good dealer, maybe you can get help. Few have had any luck with GM supporting their customers, offering to repair this defective paint. Welcome aboard though.
