hi guys, haven't been on in a while and i want to revisit my 1st post. It was about making my hunting blind into an ice shanty, well i set it up and turned on the lights in our garage and noticed that there were scratches and small holes in the sides and roof. How to I patch them cause i put a little fan on it and i went inside and i could feel the wind easily. Also has anyone ever put there portable on a sled like the shappell bay runner cause i would like to do that so i can haul it with my snowmobile.
