Hose Leaks

I have some nagging leaks at the thermostat housing. The upper radiator seems to be fine for a while and then it starts seeping again. This time I ordered the complete thermostat assy, upper radiator hose and the one that goes to the expansion tank. This will be my third thermostat top and second radiator hose since this summer. I hate to put glue or sealant on the hoses and thermostst housing, but I don't want to see a leak. Anyone ever use something like Permatex High tack or Avaition sealant on a cooling system? Yea I know your not suposed to use anything on a new hose and fitting. Ever since I replaced my expansion tank, hoses and thermostat this summer I've been having problems. Like its building up too much pressure. I've tried different thermostats and coolant pressure caps. That will teach me to do preventive maintaince on a 15 year old car!
