This was more of a problem back on the 2003 and some 2004 Vibes (the ones without the revised rockers). I didn't realize the 2005 monotones would still be affected, until I remembered the monotones didn't get the revised cladding finally until the 2006 model year. The other issue on the 2003 Vibes was when the tape would turn a yellow-ish color (for me, it was most noticable on my Frosty Vibe). This would probably be a reason you can really see this effect you mention on your Vibe as well, due to the color.There were pics of the areas where the tape is applied back in this thread:
