body color

I was think about spray my nissan fairlady z Version nismo with pearl white and I would use light grey primer for last coat. Do you think this will look good?

Why don't you just use white primer? Or if you use the grey primer, and a white base color...shouldn't be bad.

i have never try to use primer, so i don't know if it would good or not...
Is there any clear primer?

I think what you are saying is you will use gray primer on the body, then cover it with pearl white? I would say use gray primer as the base coat, followed by WHITE primer, then you can spray the pearl white over it. Spraying white top coat over grey primer will distort the top coat color.

I am new to primer. Is the the primer suppose to be last coat of the paint?
Start:gray primer-->white primer-->pearl whiteTS-45. ??

no
First primer, then paint.

Yes this is the right way.
Primer is applied to prepare for paint.

What paint do I need to use to make the paint shinny and smooth?

Clear coat.

I strongly suggest you read the questions in the FAQ (http://www.automotiveforums.com/vbulletin/showthread.php?t=63623).

There's a great deal of info there which will hopefully help you get off to a healthy start :)

so, I would also need to get Spray Lacquer TS13 Clear to make the body smooth?

Any paint can be made smooth with sanding and polishing. Like freakray said, check out the FAQ's.
