they get cleaned before they get cured so you should be good. I use duplicolour primers with my prints

It depends. If the parts are printed on SLA printers (which are getting very popular - those often are shipped with printing supports which have to be cut off), then treat them as any plastic kit parts (I wash them in water with dishwashing detergent).

If the parts are printed by Shapeways and are milky translucent color, those sometimes have waxy film on them which should be cleaned off.  I use Naphtha (Ronsonol Lighter Fluid) to clean them.

You don't need to clean prints if they were cleaned well from whoever made them, but alcohol wipes work well if they are sticky. You can primer them with just about any primer I use acrylic primer and it will help hide any layer lines depending on the quality of the part.

I print a lot of small parts myself using SLA resin. As long as they are washed properly in alcohol, almost any paint will work. 

I did find that when using Molotow Chrome,  I liked the results when applying it directly to the part vs. applying it over primer.

Many of my parts have visible layer lines. If necessary, I use several layers of primer, sanded in between, to get a smooth finish.

Try spraying it over in gloss black I think you'll be happier with that
