Glad you posted, I called the Toyota dealer and asked about the sealer...
$17.00 for a small tube?
I'll pass.

I think I will buy the gaskets and do it right the first time.

Thanks for the advice.

Anyone else here ever have an issue with their 107 draining batteries?
I've checked to see if there are lights on or accesories running when it's off, can't find anything obvious. I have looked at the fuse panel and there doesn't seem to be any thing wired into the fuse bus. I have removed the aftermarket stereo and capped ALL the wires (even the speaker wires...overkill I know but better safe than sorry.) I have not been able to find the culprit.

I think I will buy a big open knife cutout switch that installs on the battery post and just turn it off when it's parked until I can get to the bottom of it.
