One Piece has a great story and does not have a lot of filler episodes.
The spec sheets for epoxy primer state that body filler can be applied over the primer and it will hold. If you are not using epoxy primer, the filler should be applied to bare metal. When applying filler over epoxy primer, you must scuff the shine off the primer with a grey scuff pad or the filler will not hold.
