well...it will take longer to mask off the fender liner than it would to remove it.If your just masking it to clear you'll have a clear edge that will end up peeling and look like s#it.If its covered in armorall and dirt,thats all gonna end up in your clearcoat,polishing dirt and fisheyes is not anyones idea of fun far as I know,and masking tape will never stick to armoralled plastic.
Rule of thumb-Clean,remove parts,clean,sand,paint,re-assemble-It always makes the world of difference.
