Doing my first car and I would like to know if it is better to tack the hood on and then paint the car or do them separately? TIA
You can't spend your way out of poverty
If you put the hood on/in the body, then you won't get the opening edges of either properly painted. Paint it separately, but at the same time and in exactly the same way that you paint the rest of the body.
If the hood has stripes, etc., after you get the basic color on, sometimes it's helpful to tack the hood in place for the stripes (or whatever) painting.
