Dowels vs Screws to Hold Deck Down

Repaired all the missing bungs on the stern and starboard side. The process is (1) remove the stainless screw (I use a power screwdriver but will revert to doing it by hand if the screw starts to strip out. Doing it this way only 2 out of 150 screws had to be slotted with a Dremel tool before removal); (2) drill out the screw hole its entire length (about 3/4") using a 1/4" twist bit; (3) using a toothpick coat the inside and bottom of the hole with epoxy; (4) roll the dowel in epoxy to cover its sides and bottom; (5) hammer in 1/4" x 3/4" dowel; and finally (6) Using a random orbital sander with 60 or 80 grit (it's best if the sand paper doesn't have the dust pickup holes as the dowels just love to get into the holes and rip the sand paper) sand the dowel flush with the deck before the epoxy dries so that the sawdust is mixed with the wet epoxy forced into any gaps.
