I think if you would do it right away after you shoot them; it would work even better. I am thinking about keeping my small compressor in the back of my truck. I will simply use a power inverter for power. Sounds crazy, but if it makes skinning easier; it is worth it for me. I don't think the air is as effective on already frozen animals. I will give some feedback on how it works when they are still warm. Oh yeah, first I have to shoot another one...
