so I bought a dozen of the big Herters Foam decoys, I think they are 72's at a sportmans auction in Delaware. They had been burlapped but had been run hard and put away somewhere nasty. I thought they just needed paint, but after powerwashing off the mud and crud, they had been shot a bunch, the burlap had worn through in places and the metal keels were rusting and leaving gaps.
So far I have rubbed in tile mastic where they were thin or had shot holes, and done mastic and burlap patches at the tails and where they were really bad.
I just poured in some West 3M epoxy on the keels.
Paint is next
