My wife and I are going to buy my grandparents farm and it is the typical story of elderly people that let the place run down to the point where 2/3rd's of all the outbuildings are too far gone to repair. However, amongst the few remaining structures are 2, 5000 bushel grain bins that are in good shape but in some areas seem to leak around the seams where the pieces of bin bolt together. I am wondering if they can be resealed withour having to disassemble them or is it not really a productive use of my time?
