I've never painted a laptop, but I have painted a few hundred cars. If you want to go basecoat/clearcoat, go like this:
1. Scuff surface with 320 grit.
2. Clean really well with plastic-compatible solvent.
3. Spray with plastic-compatible primer.
4. Sand primer with 400-600 grit.
5. Spray 1st coat of base left-to-right. Let flash off (no longer tacky).
6. Spray 2nd coat of base top-to-bottom. Let flash off.
7. Spray 3rd coat of base diagonally. Let flash off.
8. Spray 4th coat from further away using random pattern. Let flash off.
9. Spray with 3-4 coats of clear, allowing flash off between coats.
10. Allow to air dry.
After it fully cures, sand with 1000 grit wet/dry, then 1500 grit wet/dry. Then polish with polishing compound. And then polish with ultra-fine polishing compound.
Don't sand the base color coats. Don't sand in between clear coats.
Having said all this, I would personally use spray can paint. After the final sanding and polishing, it will look like glass.

I want to paint my 87 Vert if I follow those instructions can I expect good results shooting a metalic. I plan to pratice on an old hood first.

I believe 'flash-off' is the point where the paint is less wet and more tacky, usually around 15 minutes depending on your environment. ( temperature & humidity )
So basically, you're waiting for the paint to dry enough so that when you apply the next coat, you don't make it run.

Oh, as far as the primer goes, make sure you are using an adhesion promoter primer for plastic.
Good luck
