If everything else is in good shape you may want to contact Clam and find out how much a new tent would cost. The only other alternative I can think of is PermaDri Water Shield ... I think by Birchwood Casey. It comes in an aerosol can and you spray it on. You may need several cans to do the entire tent. I've used this on boots, gloves, etc. and it works pretty good. This is only a temporary solution and spray it on outside ... it stinks for a while.
