Rear end paint

i just rattle canned mine duplicolor engine enamel. shot it with 2 coats engine primer, then 2 coats of black engine enamel. seems to hold up fine. I also like rustoleum paint as well. some guys on here go all crazy with mixing paint and shootin it out of a gun. thats fine, and im sure its much more durable, but i dont have the skills to perform such tasks.
