I need a cure for cancer!!

So, I picked up this miserable old Jetfire, pictured below for like $15. Poor bastard comes from a smoke filled home. He is majorly discolored from the cig. smoke.
So, I am going to restore this old guy to his former glory. Structurally he is sound. Just very few stickers left and that awful yellow.
I was thinking I would strip off the remaining stickers, grab a tube of http://www.amazon.co.uk/Janina-Diamond- ... B000IB0G5U or something similar and brushing the figure repeatedly till the stain comes off.
Given that this works, some reprolabels http://reprolabels.com/Autobots/jetfire.asp and this will be a truly minty, pun intended), Jetfire.
So, has anyone tried something similar on a figure this badly damaged? How'd it work out?
