Silicon vs. Plumber's Putty?
#1

I need to insert a drain top and assembly into a sink I just purchased. Should I use plumber's putty to secure the drain top to the sink, or will a bead of silicon do the same job? What's the difference?

Plumber's putty is made for this application.
It will make it much easier to remove when you need to (and sooner or later, you probably will). It will seal it just fine, and will take a very long time before it dries out.
Silicone caulk will seal under the drain also, but it will harden and stick to the sink and drain, and it may be very difficult to unscrew the drain when you need to.
In fact, you may have to tear out or cut the drain out, if you caulk it in.
Plumber's putty is the way to go here.
