I did the rest of the shields tonight. I thought I would try it without the bead blasting part, and just use steel wool. Didn't work. I suspect the old tin has oxidized and that is protecting the metal. I rarely see a rusted shield. Before the plating works, it seems I had to remove that oxide layer right down to bare steel. Then they plated fine. As they said in the manual, preparation is everything. I wish that were not the case cuz I would like to brush plate the shield holders. That would mean removing them from the chassis. Not fun!
Steve, I believe Russ has nickel plated a chassis instead of the far more elaborate chrome process. I wonder how it turned out.
