QFT. Anything lower than 180 grit has to be either sanded down to 180 grit or filled with an actual plastic filler. Also, be careful sanding with any power tools, make sure to move around a lot. If you get the plastic too warm it'll tend to cause high spots which creates even more work.
Just out of curiosity, why do you have to remove all the paint?
