Think a quart of sprayable base, and a quart of unmixed clear is enough?

No.

You will need a minimum of 3 coats of base to achieve coverage. If you get a quart of base that mixes 1:1 you would have enough and some extra in case you need to respray anything.

Unless you are using a quality High Solids clear you will need 3-4 coats to provide UV protection on those horizontal surfaces depending on your application technique.
A quart of clear that mixes 1:1 would be enough but something that mixes 2:1 or 4:1 would not be.

Ok, so I get a Quart and a Pint of premix sprayable and then 2 quarts of clear, I should be good.


Thanks for your help.

Since the section of the car is already white and the paint is in good shape. I plan on just painting over it with the gold.

Should I scuff it up first? Or just degrease it with like Dawn and then shoot color?

Wash first and then scuff to dull the clear coat with a light gray Scotchbrite pad.
