what type of paint to use

Well, this wed. I'm taking my car in to be repainted. After many weekends of sanding-priming etc...- I have had it. Time for the pros to take over. My question is what kind of paint to use. This will be a 2 stage paint job. I want a really good sealer, paint and clear. I don't care about it being original-as in Glashuit-(sp).I'm buying the materials. I know there are people out there who have experience doing this. What kind of paint are you using and you find best.
Thanks to all.........

I used PPG DBC 2001 Basecoat, it is PPG's top of the line paint geared towards european cars. Then I followed up with DCU2042, a urethane clear. For primer in the PPG line there are two schools of thought I was decising between. 1) DPX171 Self Etching primer followed by K36 or 2) DPLF followed by K36. I had my car done by a guy that was a bodyman at the porsche dealer for the 80s and early 90's then opened up his own shop. He reccommended with the 171->K36 method. These primer steps change however if you are painting over old layers of paint.
