Leaving the patina
no need for your resume man...
In a way i feel you asked for my resume, by talking about having a shitty paint job, as well as goofy paint schemes and such. Again anybody can do this kind of work with practice. Why not start with a reshoot of an engine compartment that needs a freshen up when the engines pulled for a rebuild? Small jobs like that help build experience with this stuff. I see a lot of guys on here in the restoration forum that squirt their own colors. Ask some of them for advice.
Your 65 pickup has a perfect color combo for a reshoot one panel at a time since its not metallic. I'd recommend base/clear as it makes a first timer look like a pro. That big clamshell hood can be done off the truck sitting on a set of sawhorses, to get a better angle at it with a paint gun.
As far as patina goes, does a car with patina look good? Well it depends i guess. Manufactured patina no. Original patina yes, clearcoated original patina no. Those are my opinions. I also think it looks good on cars from the 30s to the 50s. Personally i'm not a big fan of patina on 60s 70s cars. Out here in Texas we call it the Texas two tone. Burnt to a crisp on the top, paint left alone on the sides.
