I am going to do it haf way then: Body car filler through the two
holes
with grey stuff already, hoping they will bond somewhat, and a good
bed
of silicone all around the base.

A bed is not the same as a bead.

Good point, I guess the poster before meant a good "beading".

I understand, I will inject silicone around from outside once the pan
is touching the floor, I won't lay a bed of silicone and rest the pan
on top.

I (mis)understood the opposite - that you were intending to only apply a
bead of silicone as you said "all around the base" rather than "all over
the base".
