Two-Tone Layering Question

Well, the clear coat has started peeling in a lot of places on the 5 year old $500 paint job on my '68 4 door. The roof is white, and the clear has faded on it and peeled. All of this happened in a very short amount of time - about 2 months. First noticed the first peel, then every wash gets worse and worse. Anyway, I want to repaint the car.

I am all about low downtime, so I'd set probably a week aside to pull it into my shop when it becomes empty, peel all the vinyl off with a vinyl wheel, and remove what I can.

There's a couple things i want to fix - pull a dent on the driver's door, and fix the trim holes. As far as I can tell the previous work was to pull the strips off the side of the car and just fill the clip holes with bondo or something. They were invisible 3 years ago, but now each one you can see a recessed ring that gives away the hole. So I want to put some kind of backing on those and epoxy them.

The pillars on the rear of the roof I know are likely bondo'd but I'm going to wait and find out.

Anyway - on to my question. Bronze metallic was not my first choice of color, but it looked nice so I left it.

I want to recolor Plum Crazy with a Urethane. On top of that though, I want the roof to be gloss black, and to have a painted on gloss black stripe, as well as paint the window frames on the 4 doors black - it gives a slight illusion to being a no post. Then the rear -trunk trim I am taking off, and painting that portion black as well, and having a sign painter friend paint "Dodge" in cursive script in silver and black.

So my question is, how should I layer this? My thought was to spray the black roof, spray a black splotch across the trunk and rear fenders, and then tape off where the stripe will be, tape off the roof, lay down some kind of base, and then the purple. Or would I do purple, tape off the rest of the car besides the stripe, lay down black?

Or something else entirely? My worry with the black on top of the purple is that the paint layer will be raised slightly and crisp and it'll just look vinyl. Basically I don't really want to be able to run my hand down the body and feel the stripe, is that possible?
