Now that I am getting older and I tend to do what I like, meaning, I would rather have something that either looks better, or drives better, I guess after reading this post, I dont mind a little mold under the carpet. (for those that cannot understand the last part of the sentence, I might not mind a color change on a car). Of course it you take a car to bare metal and remove every inch of the original color, (remove the mold) so what?!?! But that is a lot of $$$ and work. Back to my Escort wagon, it was painted yellow and if you looked close when you opened the doors, you could see the tape job and the red. SO, it you are changing the color, make sure you "change" the color.
