Rust is NOT a "patina"!

Cold-bluing is not a "patina" either.

Thank you for letting me vent.(I wish I could post some links from the auction side.)

(And for anyone who may want to get technical, when I refer to rust, I'm talking about the red oxide when a metal finish is being destroyed -- and when the original finish, which may have been a stable oxide, has been destroyed or removed.)

    Yes, the Gas Monkey Garage doesn't understand the word "patina" either.

    I wonder how dissatisfied their customers are going to be when that rust starts popping through the clear-coat they spray over it on some of their builds.

    (I don't mind the "original" look, but they have to understand that one can't leave red oxide and expect it to be stable.)

    If I was to buy a car without good paint I would much prefer it sanded down and sprayed with grey primer, I think some vehicles look good in grey primer.

    I've always liked "sleepers" -- a faded finish with rust spots can be good for that, but the rust needs to be "faked" or stabilized with "reformers" -- in which case it won't be red-colored anymore.

    Just clear-coating red oxide won't last long term as the water molecule attached makes red oxide an unstable surface for paints/sealants.

    Patina is for some 'non ferrous' (no iron) metals.

    Rust is for 'ferrous' (metals w/ iron) metals.

    Glad you said that- we do some rust patinas Black patinas, bronze patinas that are very expensive to do. The difference lays on the finish and coating.
