PPG or Omni Experience?
Stick with one paint line. PPG and Dupont have "codes and formulas" for older paint codes. They are usually not the best. I sprayed PPG for 20 years and was glad when I didn't have to anymore. Omni is transparent and will require double the amount to achieve coverage.
I did always have good luck with PPG's clears... 2042 for production and 2002 for restorations.. have heard good things about 2021 also.
I have an original B5 Blue Demon, and had it mixed in multiple formulas by my jobber in Omni, and DBC.. neither was remotely close.
I have sprayed Spies Hecker and their basecoat was good... the production clear we used was garbage... High solid clear, "ultra" high solid catalyst... Sprayed like glue and was hard to lay down. I am sure they have a much better "restoration" clear.
My all time favorite product that I have used and am currently using is Akzo Nobel/Sikkens Auto Base. This is a solvent basecoat and is far superior to any PPG I have used. Coverage is great, sealers are awesome, and the clears are some of the best I have used. I use a color camera daily and it hits probably 95% of the time with only pressure adjustments needed to get the perfect tone you need. There really are no need for formulas pre-1990 when you have a sample that can be scanned.
Here is a Fusion I painted this morning. And the BMW I sprayed the hood and matched to the bumper better than OEM.
