It is becoming very difficult to find any good quality paint in Calif. They are putting the kabosh on everything. It seems that these water base paints are what are being pushed. The paint shops have had to change all their painting methods and equipment.
Maybe check with some PPG vendors in Arizona or Nevada, out of state you might be able to find what you need. Having it shipped might be a problem because it would be a hazardous material. I know in the Bay Area they have really tightened down but I was able to find some PPG paint just south of me. That was a couple years ago though.
Automotive paint is expensive enough, don`t cheapen out on the front end, and then later feel like you shot your self in the foot if it doesn`t hold up, or the end results aren`t quite what you expected.
Single stage paint will look good years later where Clear Coat will be pealing and the vehicle looks crappy. with a single stage, just give it a coat of wax, and she will be shinning like new.
I painted the 85 Astrial Silver and Clear Coat, and it has fallen apart, and I used PPG. I have been wondering if there is a Silver that is single stage for next time I shoot her.
I painted the Datsun PU back in the 90`s with PPG Deltron. all I have to do is give her a coat of wax/cleaner and my hands are red, but she shins like the day I first painted her. That is another good paint we can`t get anymore.
