I just had my 4 speed shifter insert plated. Chrome is beautiful, but on close inspection the sharp edges of the larger chrome strips are not as sharp. Once the plate was reinstalled in the larger piece, this slight loss of sharpness was a not a factor even though the larger plate, retained its original chrome (I lightly polished the chrome on the larger piece with a moto tool w/ buffer wheel and metal polish).
The dull section between the ribs was redone with "bumper chrome" paint. (Mask off everything but the ribbed area and paint right over the ribs as well. Paint application is best on a warm day, holding the can about 12 inches away, spray 3 to 5 light dusting coats gives an appearance that is very close to the original. Before the paint cures use a very thin piece of fabric applied stretch tightly over a small sanding block, apply a little lacquer thinner to the fabric and lightly wipe along the surface of the ribs. ) The ribs end up nice and shiny and the channels remain with the paint.
The thing isn't perfect, but it does look like a reasonably well preserved original piece.
The real problem with plating these things are the pits, and the more there are, the more likely that they will get bigger when the piece is prepped for plating. It's very difficult to fill in the pits with chrome/substrate without filling in the grain and losing the sharpness. I did mine because it was in pretty good shape to begin with and I wanted that C4ZB on the back...which of course you can't see - but I know its there
