Decoy Repair Help

[tjwatty]

I guess I should have elaborated, We hunt on the Mississippi in a public area. We lottery draw for blind sites which are ours for 2 years. If I'm not in my blind by 30min before shooting time anyone can hunt there. We have approx. 600 decoys out from 3 to 5 days before the season until we get iced out, therefore WE DON'T SHOOT OUR OWN DECOYS but other idiots do on occasion.
Most of my leakage comes from splits along the keel and seams. I have used the spray foam in the past and that seems to get one or two more years but that foam tends to shrink over time and then the dekes partially fill and look funny in the water.
The really sad thing is that it seems the super-mags are more susiptible to damage, figures, their the most expensive. I haven't tried hot glue sticks yet, I think I'll give it a try.
