Good site --
If you want a gentle intro to plating, Caswell provides a substantial amount of free information and a beginner's guide.

This is one of the best resources -- Using this guide and starting small, I graduated from basic equipment (battery charger) to plate small brackets and such, to a nice Llamda 100 amp DC power supply for plating bumpers and large trim.
