Sand the plastic part using progressively smoother wet & dry paper till you get rid of all the scratches etc. Wipe on a couple of coats of the renovator. Polish off using fine steel wool and then apply further coats of renovator. Hey presto... a shiny new looking tank !!

That's a nice piece of work. Tell me more about the plastic renovator. Who makes it and where can I get some on this side of the pond? How fine of a sandpaper do you finish with; 600, 1200 or finer?
