Ok what I want to do is have an object start on the hood and have it go down on the fender cadi corner. I'm not sure how to do this in fact I have no clue how to begin doing it. I'm using master skinnerz template in that helps at all. I think it's called wrapping? But how would I do it so it would look right?

Trial and error. Place it, move it, check it, move it, check it, move it, check it, nudge it a pixel, check it, etc.

That's the only way. Use the wireframe overlays to get approximate alignments, too.
