Let's talk about original paint, Lacquer or base coat/clear coat Options

[442nd914s]

After 5yrs of restoration I'm at the point of painting my 73 Zambezi green. While most people would take this time to change the color or put flames, I want to keep it as much original as possible. For those who can remember original 70s Porsche paint, or those who are fortunate to have a pristine original paint on their cars......what type of paint was used in our cars? Lacquer or base coat/ clear coat? I've read articles about both pros and cons on the subject, but never have seen it with my very on eyes.
What's you guys opinion? Not only what would look good, but why would it look good and last the remaining life of the car. Keep in mind that my car will not be a daily driver, but a historic non concours show car. I plan on the occasion local drives and attending local car shows. No Peeble beach concours car shows.
Thanks for your input. Much appreciated it.

Use Imron on my plane and trucks. Read the MSDS and don't see the stuff reported above. It is a polyurethane, still sold, as well as many others like it. I know that in some areas in CA it is not VOC compliant. We had to move some shop painting from LA to Kern County due to this. VOC's don't seem to have a reported link to cancers.

what i have learned in my industry is anything that good is going to kill you. (IMG:style_emoticons/default/sad.gif)

VOCs unfortunately do have a link to cancer.
volatile organic compounds.
its now a big thing in housing. your carpet can kill you! etc. it goes on.

but ........it is good stuff. imron.
probably the high point in paint durability technology.
all down hill from there.
there are some problems connected to it in terms of it shrinking away from tight contours and cracking with time. but thats a measure of just how tough it is too.

as to base coat and clear coat.
aus is the test bed for the world.
highest UV levels anywhere, maybe chile, south america comparable, only the south pole trumps us. you want to feel the sun burn your skin in summer after 5 minutes, come here. i wouldn't advise it.
cars go to crap here within 5 years in some cases.
clear coat failures line the streets.
hyundais are the worst.
