I have heard the plastic renew stuff is great for a sale. Only. Also, Pledge is good. Even WD-40. Mop and GLo works well. Some of the Acrylic No Wax stuff looks really good. Sticks pretty well and fills in the smaller scratches. Brightens it up too. I also heard a good 10 hour wet sand works well.

 

about changing the picture by the name,just go to profile and at the bottom you can change it

 

This is an old auto-body type trick. Find a wax crayon that is the same color as the scratched paint (plastic) and color it in, the wax fills in the gap and is not susceptable to water. It probably wouldnt hurt to use something like turtle wax over top of it too.
