Thanks for all the info. My truck was too far gone (IMO) so now it's got shiny new paint. My resto buddy that I had help me replace quarters and wheel wells, sill, etc... does a good faux "patina paint job". He shoots primer, single stage paint, sands it back to
imitate natural weathering and induces oxidation with an acid mixture he made up. Then he cleans it and does pretty much the same BLO preservation treatment to the whole thing. Sometimes he uses wax. (he hates when people clear coat patina'ed cars. I do too).
My buddy's work (forgive the non-Toyota truck):
The body panels were all mismatched with the bed and cab.
Beyond looking weird out of the gate, clear coats require a chemical bond to function. That means they need to be applied
before the paint is cured. Clear coating old paint (even in good condition) results in cloudy de-lamitation after not very long. It simply won't stick. Then you are stuck removing it, and probably just janked-up your sexy patina that
was the way God intended. Now you're going to hell.
My friend charges the same (or a little less) for a "patina paint job" as a regular one, and although I LOVE the look of an old truck, I feel like I can usually tell when they are faked. Maybe it's because I work in Photoshop all day, and I pay very close attention to realism and following that to fake things that don't exist in camera. If we had gone down that road we would probably not be friends anymore. I would have been VERY particular about the faux aging. With a standard paint job, the outcome is pretty well defined.
After the original paint has faded, my personal order of paint preference (no offense intended if you don't agree):
1. Naturally patina'ed and preserved truck (not just any one will do, the acceptable examples are not a dime a dozen)
2. Single stage painted truck
3. Faux patina'ed truck — the right way
4. Dual stage painted truck (to me, it does not look right on a vintage vehicle, even in "original" colors).
5. Naturally patina'ed truck — clear coated
6. Faux patina'ed truck — clear coated
I DO however have a vintage front license plate I will be applying the 89nOlder preservation guide to before I mount it.
Just need to find a vintage patina'ed font plate holder to match.

Great thread.
