We used toothpaste once to "re-transparent" a bubble on a Bell-47
helicopter:
A new guy wanted to clean it extra well and used something like scotchbrite
but harsher. With all the foam from the extra-soap no one saw the damage
until the bubble was dry - it was the perfect instrument trainer!!
A couple of hours polishing with Cogate's finest did the job!!

I believe the ingrediante that works is baking powder, most likely in
conjunction with the movement of the toothbrush!!
(on the bubble we used cotton-pads...)
