I am building a 3'X 5' Wooden Baitwell to sit on my dock to keep Bait in. It is 3' Tall. I am in the process of finishing it an I am about to start filleting so I can fiberglass the corners. How big should the fillets be? Can i use a mixing stick to make them? That is what i would prefer beacuse I only have two things of Filleting Blend(8oz.) and I am running low on funds. Thanks!<br /><br />Sonny
