I've had the same thought about mine, until I saw my girlfriend at the time's 05 silver corolla which had collision repair... trying to save a penny or two they used basically what you're describing.... talk about horrid. Not to mention the cold hard fact that red is the most expensive color. lol.
thats why I love minez so much, red it is not. IMO, if you're gonna do something-- do it right and be done with it.
(mostly because 3 years afterwords she went back home to visit her parents and they redid the whole back end where the crappy paintjob was X-D )
