What kind of paint are you using, where are you painting it, and how are you cleaning/prepping the plastic?

its duplicolor vinyl paint its flat black and im painting the vinyl (door panels )

are you asking why it isnt shiny? if so, it may be the fact that you are using FLAT black...try using somthing along the lines of 'glossy black.' this will give it the shine you are looking for
