Changing paint colors?

[mp3deviant721]

Like say, going from red to black or blue? I know there is going to be engine compartment stuff removal and engine removal, the only thing I'm concerned with is how hard it would be to keep the red concealed beneath the new color. I would most likely be doing this in the coming fall at school as a class project. Please note, however, that this is for a truck that I may buy shortly here and not for my current one. So I might not even do it.

just make sure its all scuffed with either a red scotchbrite pad or 320 grit sand paper, clean it real good, prime it and paint it
