I know it may sound crazy, however, preparing to make a mold and your original part is not perfect. Sanding it to make it as perfect as you can, because the mold will take on any imperfections that are present in the part...keeping in mind, that this mold will allow you too pull several parts from it......just wanna confirm my thinking...This stuff is ex$$$$$, too x$$$sive to make many mistakes 
How/ would you handle the sanding process, just as you would with any surface. Different grids of sand paper, too obtain the surface you desire?
Because too go out and buy all new parts, to make fresh molds would be$$$$$.......

Niceadvice Joe! When working with smaller parts, I just make sure the gelcoat formy mold is a little thicker, then buff them outta the mold surface since youneed to work the mold through the grains anyhow. after going through them allyou may already be past those imperfections.
Inmy experience in body work I can tell you the level of perfection needed is notalways down to the .025 mm.
