Do a search for 'slick chick' and a bunch of threads regarding this game will pop up. I restored this game from ground up recently (I actually think yours may be better condition).
there are threads for restoring cabinet, the play field and new labels and special lock available that I put up.
Legs are correct you just need to put overnight in Evaporust and polish.
I make a master stencil for the repainting for all games but this is a simple game and the paint is probably still there although hidden. If not I can provide a copy when I return home if you really need.
Your painting method seems fine.
