After assembling the sword I started priming it using black gesso. I have had good luck with gesso on my wood sword props and it did not disappoint this time. After eight coats I used 240 grit sandpaper to create a smooth surface. After sanding I used food filler to repair some of the imperfections both in the wood hilt pieces and the foam blade.
I sanded the filler down, then primed it again. I still have a circular piece to add to the base of the hilt and add details to the pommel and prime that.
