I don't use setting tape due to problems with variations in glass thickness and setting tape. This is not a problem for a glass shop, as they have a complete inventory of the different thicknesses of everything at their fingertips.
I use black RTV. I let it get tacked up before I slide the glass in. This helps keep the glass stay centered in the channel.
RTV has enough adhesive properties to keep the glass in place. Urethane adhesive is stronger, but the guy who has to deal with broken glass in the future will need to find a new channel, and will try to hunt down and beat the guy who did him thataway. Urethane in a tight channel is nearly impossible to clean out.
