Given the Presta valve and its air port is so small, I just:
1) Deflated the tire(s)
2) took the hose off of my Performance brand Hurricane floor pump (@ the pump end) to allow the silicone to displace the air in the head/hose as the silicone is relatively viscous
3) took the innards out of of the "head" of hose [the stuff that lets you switch between Presta and Schraeder]
4) filled the head and, indirectly, some of the hose with a "seemingly appropriate" amount of silicone
5) put the hose back on the pump
6) made sure the tire's Presta valve was @ the bottom of the wheel (so gravity can assist as opposed to hinder the flow of silicone)
7) hooked the pump up to the Presta valve nice and tight to avoid a leak of silicone (and of course air)
6) filled the tire back up essentially pushing the silicone in along w/ the air.
Seemed to work OK.
