real good paint for california

I'm ready to have my 1970 duster 340 repainted.
The body shop owner said he was going to use PPG Omni paint.
I have looked on the PPG site & find that it's a budget paint.
After almost $9,000 in prep work I'm not sure about using a Budget paint.
Any suggestions ?

PPG Deltron DBC is what we use at our body shop. Its a 2 stage paint, a basecoat with a clear coat. its what is used by any new car manufacture.
