The alcohol method requires some elbow grease, but avoids messy and caustic chemical strippers that will require an alcohol bath anyway to produce a paint ready shell.
Leave the shell submerged in alcohol for a day then scrub with a tooth brush. Repeat for the inevitable hard to get places, then a final alcohol rince and let dry. Result is a sealer/ paint ready shell undamaged by coarse abrasives. Scuffing pads and paper are a definite way of removing fine detail relief and should be avoided.
