$25 for a near life-time supply.

Sometimes the coolant hoses that have metal ends with o-rings on them can develop a bit of oxidation "crust" on them. This lubricant not only overcomes that crust but also really helps the rubber o-rings slide in, and super tight, new rubber hoses sliding over metal barbs.

I am going nekkid.

Reason: there is no sliding here. The gasket is inset on the pump in a groove and comes that way in the box... not flopping around. Not need to be held in place. The pump is flat-mated to the chassis... no sliding into anything... just face-to-face. I don't think even I can screw this one up.

Oh no, you’ve woken the gods of so easy nothing can go wrong! To save you I’ve poured two single barrel bourbons, one for me and one for Thor the god of self car repairs.

Try this. Sealube P-80 . amazon or probably at a pool and spa shop. $5 to $8 depending where you go. No silicone or PTFE. Water soluble , good for suspension bushing etc. The purists will complain. Just my idea and opinion.
