Toto sink install question

[LittleBlueTruck]

I'm installing a pair of TOTO self-rimming sinks in a bath vanity. The instructions say to just set the sink in the hole (with no sealant applied to the bottom of the sink) and then seal around the edge. My questions are:

1. Is this right? Most generic instructions that I see suggest applying a sealant to the underside of the sink before dropping it in. This way seems easier since I can position the sink more easily. However, I want to do it correctly.

2. Assuming it is correct, what type of sealant should I use around the edge of the sink.

Thanks in advance for your replies.

Is that a laminate top? I had a marble top.

I masked it off and used 100% silicon, around the edge of the sink.

The vanity is a dresser that was stripped down to bare wood and then refinished with Waterlox.

We drop the lavs, install them to plumbing, and at the very last use clear polyseamseal on them.
You can do Silicone too. I don't.

What Terry said!

Thanks for the advice. I went with the polyseamseal and it went well.

The advantage of the polyseamseal is that it will remove easily when and if you want/need to do so, and won't leave the same kind of residue as silicone caulk.
