Answer
Hi Amir,

Ideally, It's best to sand and seal with an Acrylic Urethane Sealer or Epoxy Primer (If you are talking about black e-coat primer, most sheet metal aftermarket parts come this way). Then, depending on what type of paint you use will change whether or not the part needs clear coated. Base-coat paint needs clear coat while there are single stage paints that dry glossy and will not need cleared. Your needs may vary depending on the color. My recommendation would be to go to a automotive paint store and get some help deciding what type of paint you should use.
