stop going to the drive through car wash, then go visit the Junkman on youtube. Or join the Meguiars forums and review their car care videos. Or go to Adams website and view their videos.
There is also a forum here on C5 dedicated to the subject and you will find a smorgasboard of ways to keep your Camaro spotless.
