Took it all to bare metal. Painted the red primer first, thick, then before it completely dried applied the dark grey. Putting the coats on too soon caused the grey and red to separate, looking like cracks. Wet sanded with 400. The skull is hiding a dent. Bought a bunch of them at a hobby store for $1.68 a piece. Cut it in half, filled it with bondo glass and molded it in. Coated it with fiberglass resin. The rust streaks are real. Fine steel wool soaked in vinegar and salt. Put the wool in all the holes and sprayed them several times a day with the vinegar in a spray bottle.i pushed on them several times a day, squeezing the liquid rust out and letting it run down the car. It stained good, dont wipe off.
