Im trying to make a sword and was wondering if my technique is correct, i heard if i keep applying primer and sanding it will turn out really well, and so i did but i also put wood filler (in some videosbi see they put a shit load of wood filler inbetween and was thinking of doing the same) in some of the gaps to make it smoother but there are still small bumps around the sword, will they go away if i continue?
