Nice job on that cabinet. Makes me want to strip mine and restencil. Do you have the files you made? Pretty decent color match too from what I see. I'd be interested in knowing the stock rattle cans. Looks like you started with a pretty good example for the playfield. Mine was pretty rough in comparison. Lots of touchup work.
