Hmmm boy an Imature that will be some good eats. My hunting partner says it doesnt matter how many you have in the air at the same time it only maters that the moose goes down!
Silicone is your friend but if you have to bag the foam use drycleaner bags they are much nicer to use and you don`t need to tear them out as they won`t make any noise. As was said earlier careful attention should be paid to the seats. If that burlap is rotted and it almost assuridly is fix it...
