Im redoing the paint in my engine bay on a 70 duster. going with the ol' mopar green. Anyways, about how many layers of primer do I need to shoot? You could guess Im not a body guy. I used 80 grit to take most of the original paint off, then shot it, then used 400 to take it down a bit and re-shot it. Do I need another coat? Also, about how many coats of the paint should I lay down? How much paint do you suspect I'll need? Will a pint get it done? Or do I need a quart? This is my first real paint job. Thanks!
