Well, after losing out on three tanks on Ebay, I decided enough already, went and purchased some Kreem.  Followed the instructions, and making a temporary block for the petthingy space at 11:30 pm was fun.., didn't realize the process was an overnighter..or all dayer if you start early enough.  Seems to be working, no more gas leaks (yet).  Downside is you really have to be careful, between the fumes and the white kreem liking to attach itself to anyhthing it comes in contact with.
