So I am making a rolling kegerator out of a trash can. Inspired by BierMunchers Rolling Kegerator.
I found a great rolling trash can at Wally World it's this one but at Wal-Mart it was $18 http://www.amazon.com/Pioneer-Plastics-TuffCan%C2%AE-Rollout-Container/dp/B002SPG1H6/ref=sr_1_5?ie=UTF8&s=home-garden&qid=1282344314&sr=1-5
Its very tall and square, the wheels aren't big so that hump in the back is a lot smaller than all the other cans I looked at.
I can put a flat piece of plywood in the bottom to make a flat floor with no hump and still have 29" height of space. So I am gonna put a floor in it and then fill the cavity under it with spray in expanding foam.
I was thinking that for insulating the sides and the top I could use 3M spray adhesive and use it to mold this stuff to the walls: http://www.homedepot.com/Building-Materials-Insulation/h_d1/N-5yc1vZasbsZ60qgx/R-100020855/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053#BVRRWidgetID
It's like bubble wrap with a mylar coating, it seems pretty tuff. I could do a couple layers of it. I am not hoping to keep ice alive for 3 days but maybe keep 3 kegs cold for a day.
Good idea? bad? Big question is if this stuff will adhere to the walls?
