Mike your barracuda looks like it has weathered natural and well. Nice car.
Now get some paint on it. Kidding.
All my cars are so over patina'd I won't even post pictures on the site from embarrassment.
I think it is better suited to 40s and older cars. I am building a model A that doesn't have a lick of paint left on it and it won't get any. The car is to rough and would cost a fortune to make paint look good on it. It is cheaper to just leave it alone.
