i got in an accident the other day and i need a new bumper and hood. those i am getting from the junkyard. i dont have enough money to paint everything now but after the accident lots of paint came off my fenders to expose the metal. i dont want my fenders to rust so how should i cover it? paint it with primer? i am not sure the best way to tackle this job. however in the summer time i will repaint the entire car.
