How to improve the finish of the peel ply side after resin infusion

Hey guys I'm looking for some techniques on how to make the rough side look better. The parts I make are molded, but do not have any intricate or hard to reach areas

I don't need an A finish so I have already ruled out the more difficult techniques like closed molds or fusing 2 finished parts together.

What have you guys tried? What ideas do you think would work? And what is the difficulty and finish you got?




Thanks for the help,
Lance

A quick and easy way is to sand the peel ply finish smooth, then blast a couple thin layers of lacquer over the top.  You can actually go far enough with a few layers of lacquer to make the back look almost as good as the A surface but only go that far if you are also lacquering the A side or it will stand out too much. 

You can also skim over a thin layer of resin to smooth it out.
