Tef-Gel or Dura-Lac for spinnaker pole track screws?

I'm currently installing a 6ft spinnaker pole track on the mast.

Drilling/tapping the 20, 5/16" holes was harder than I thought (mast raised on floating boat). If the drill bit walks just a bit, the hole alignment can be challenging over the course of 20 holes. In the end, I got all the screws to fit, but I had to enlarge about 5 of the holes in the track itself (by 1/64 - 1/32) to get the alignment right.

I have both Tef-Gel and Dura-lac in the tool kit, so I can use either one when installing the screws. I keep reading that Dura-Lac is very hard to work with. Was wondering why that is. I know Tef-Gel is easy. Is one preferred in a "permanent" application such as this?

I used Tef-Gel on all the fittings I reinstalled on our mast last summer. I'm pretty sure I researched it at the time and found that Tef-Gel was highly recommended for that application. I haven't used Dura-Lac but have used Lanocote in the past. I definitely prefer the Tef-Gel to the Lanocoat. It seems a lot stickier and definitely smells better. Costs more too...
