I know the basic answer....plug one end of the keel, fill with sand, plug the other. I've done it before, but the calk that I used to seal the ends didn't hold very well.
So my question is: what is the BEST way to seal off the ends? What is the best calk?
Also, I have a few decoys that have cracks and need repair....what have you found to be the best "glue" to seal off these cracks?
Thanks in advance.........
