-if you haven't siliconed that spot up yet you ought to consider taking a Q-tip and swabbing the area with some thin green or red loctite----just let that seep into the leak area.
-You'd probably have better results with the loctite if you try to clean it good with some sort of quick drying brake or carburetor cleaner--and maybe use a heat gun to warm up the area then swab the loctite onto there.
-Or even use a smear of JB Weld.

-There is a product called
www.techspray.com that sells freezer in an aerosol can part #1672-15S where 15 is 15 OZ.
-This stuff says it cools to -62F----I have tried it and it's quick and will put a frosting coating on metal parts in just seconds.
-It's available at Allied Electronics for about $14 a can but it's real handy to have in your tool box at remote places like Bonneville.
