I don't know what would match the stock color, it seems to have a bit of purple in it. As for clear, I highly recommend Minwax Satin Polyurethane (gold spray can). It is very fuel proof (much more than lustrecoat) and goes over decals and other paint without worry of bad reaction. On my CMP planes that I did not repaint, I used the clear to set the decals or other paint touches like invasion stripes. On my Hellcat, I totally repainted it using Testors modelmaster colors and put the clear over top. It is holding up well after a couple seasons of flying.
