Use 1000 grit paper and sand the shiny off the clear , and I wouldnt go more then 3 coats of color as DCC is a fast covering paint.

Let it dry for about 15 minutes then carefully pull off the tape ( if it strings when pulled up let set for a few more minutes) as this will help the edge flow smooth . If you let it dry overnight you will have a harsh paint edge.

You might even get by with 2 coats as it does cover well .
