Tim,
You might take a look here :
http://www.ppg.com/cr-refinish/phase1/frmHome.asp

And click on the Product Information -Pant lines - Deltron , then on the left side , you will see " View by Category" click the drop down window till you see " other " then look to the bottom for the DX metal conditioners/ product sheet . it will pop up a PDF file and you can read up on what you need .
Same goes for the paint you want to use , I recommend using DBU or DBC base coat clear coat system ( which is the Deltron Line ) .

Take a look around that site and read on the DPLF epoxy sealers for using after you have the metal conditioned , then I recommend using K-36 or NCP 271 Corrosion resistant primer over the DPLF .

I can get you the PPG color number for the Lamborgini later today.

Hope this helps
