I have added a new tip on my blog on cleaning and polishing clear parts as well as removing scuffs or unwanted seams using Meguire’s PlastX cleaner and polish. The photos are the before and after on removing scuffs from a B-17 nose and removing the seam on a modern jet canopy. I prefer doing this rather than dipping in Pledge Future. The clear parts appear clearer with a lot more shine and resist dust when sitting on a shelf for a while.
