When painting a vehicle, why do you put down a base coat and why does the color of the base coat matter?

Question

I'm talking about after the primer.

Answer 1

First color coat or base allows you stand back and see if the body work is straight enough. The color of a base coat matters when your are shooting candy colors as the base color shows thru the candy colors. Color of the primer matters also red primers tend to bleed into light colors use light gray on light color paint jobs.

Answer 2

Base coat/clear coat is an entire painting system. Unlike synthetic enamel, the base coat does not shine as much. It is designed to be used with an additional clear coat applied over it. You could use primer, and then a synthetic enamel over that and be done. You will need: (Primer) catylist, reducer. (Paint) catylist, reducer. Use laquer thinner to clean the spray gun. If your car had laquer paint, you can use anything to go over it. BUT, if it was a base coat/clear coat urethane, you MUST use a urethane based paint over it. Whatever was on the car, it's best to use a mid-coat sealer after the primer, but before the paint. This ensures that there will not be a reaction between the chemicals of the different paints. Any good automotive paint store can give you all the details about different paints, application tools, and mixing instructions. I recommend Ditzler-PPG base coat/ clear coat system, and DeVilbis paint spray guns. (Model JGA)

if you didnt squirt the primer down first your paint would flake off like a earl schieb job. the paint sticks to the primer
