I tried PAM, and it seemed to me to be beading up,
rather than wetting the
silicone surface. I decided not to trust it, and washed it all off, before
using the Vaseline. I'm sure there's some product made for this, and
"only"
$12/bottle...
Close it's only $14.60 a can.

Is Silicon RTV better than Urethane RTV for this application? The
advantages of one over the other weren't clear from the website
descriptions.
